Concentric Groove
The overwhelming majority of records manufactured have been of certain sizes (7, 10, or 12 inches), playback speeds (33, 45, or 78 RPM), and appearance (round black discs). However, since the commercial adoption of the gramophone record (called a phonograph record in the U.S., where both cylinder records and disc records were invented), a wide variety of records have also been produced that do not fall into these categories, and they have served a variety of purposes. Unusual sizes The most common diameter sizes for gramophone records are 12-inch, 10-inch, and 7-inch. Early American shellac records were all 7-inch until 1901, when 10-inch records were introduced. 12-inch records joined them in 1903. By 1910, other sizes were retired and nearly all discs were either 10-inch or 12-inch, although both sizes were normally a bit smaller than their official diameter. In Europe, early 10-inch and 12-inch shellac records were produced in the first three decades of the twentieth ...

Gramophone Record
A phonograph record (also known as a gramophone record, especially in British English), or simply a record, is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the name vinyl. The phonograph record was the primary medium used for music reproduction throughout the 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the record left the mainstream in 1991. Since the 1990s, records con ...

Compact Disc
The compact disc (CD) is a Digital media, digital optical disc data storage format that was co-developed by Philips and Sony to store and play digital audio recordings. In August 1982, the first compact disc was manufactured. It was then released in October 1982 in Japan and branded as ''Compact Disc Digital Audio, Digital Audio Compact Disc''. The format was later adapted (as CD-ROM) for general-purpose data storage. Several other formats were further derived, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video CD (VCD), Super Video CD (SVCD), Photo CD, Picture CD, Compact Disc-Interactive (CD-i) and Enhanced Music CD. Standard CDs have a diameter of and are designed to hold up to 74 minutes of uncompressed stereo digital audio or about 650 mebibyte, MiB of data. Capacity is routinely extended to 80 minutes and 700 mebibyte, MiB by arranging data more closely on the same sized disc. The Mini CD has various diameters ranging from ; t ...

Isis (band)
Isis (sometimes stylized ISIS) was an American post-metal band formed in Boston, Massachusetts in 1997. The band borrowed from and helped to evolve the post-metal sound pioneered by bands such as Neurosis and Godflesh, characterized by lengthy songs focusing on repetition and evolution of structure. Isis's last studio album, ''Wavering Radiant'', was released on May 5, 2009. Isis disbanded in June 2010, just before the release of a split EP with the Melvins. In 2018, the group reformed as Celestial for a one-off show to pay tribute to Caleb Scofield. History Formation, ''Celestial'', and other early releases (1997–2001) In Boston, several sessions of experimentation led friends Aaron Turner (guitar/vocals; also the owner of Hydra Head Records and its subsidiary, HH Noise Industries), Jeff Caxide (bass guitar), Chris Mereschuk (electronics/vocals) and Aaron Harris (drums) to form Isis in autumn of 1997. As Turner stated, "Isis formed as a result of the dissatisfaction with ...

The Red Sea (EP)
''The Red Sea'' is an EP by Isis. An expansion of the sound pioneered on their previous release '' Mosquito Control'', this EP offers a slight evolution toward the direction Isis would begin to take with their first full length, '' Celestial''. The three songs which make up the original EP (tracks 1–3) are tied together with spoken word samples from the short-lived television series '' Hotel Room'' (specifically, the third episode, entitled "Blackout"). The song "Ochre" contains a sample from the film '' Dead Man'' by Jim Jarmusch, and is a reading of a portion of William Blake's poem " Auguries of Innocence". The album was first released on CD and 8" vinyl. The CD (and later 12") versions of ''The Red Sea'' contain the four songs that made up Isis' 1998 cassette demo (as bonus tracks); electronics are by former member Chris Mereschuk on those songs. This is the first release with Jay Randall ( Agoraphobic Nosebleed) on electronics and backing vocals (he also appeared on I ...

Bluebird Records
Bluebird Records is a record label best known for its low-cost releases, primarily of kids' music, blues and jazz in the 1930s and 1940s. It was founded in 1932 as a lower-priced RCA Victor subsidiary label of RCA Victor. Bluebird became known for what came to be known as the "Bluebird sound", which influenced rhythm and blues and early rock and roll. It is currently owned by parent company Sony Music Entertainment. History The label was founded in 1932 as a division of RCA Victor by Eli Oberstein, an executive at the company. Bluebird competed with other budget labels at the time. Records were made quickly and cheaply. The "Bluebird sound" came from the session band that was used on many recordings to cut costs. The band included musicians such as Big Bill Broonzy, Roosevelt Sykes, Washboard Sam, and Sonny Boy Williamson. Many blues musicians were signed to RCA Victor and Bluebird by Lester Melrose, a talent scout and producer who had a virtual monopoly on the Chicago blues ...

Whale
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. As an informal and colloquial grouping, they correspond to large members of the infraorder Cetacea, i.e. all cetaceans apart from dolphins and porpoises. Dolphins and porpoises may be considered whales from a formal, cladistic perspective. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest non-cetacean living relatives are the hippopotamuses, from which they and other cetaceans diverged about 54 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have had their last common ancestor around 34 million years ago. Mysticetes include four extant (living) families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), and Eschrichtiidae (the grey whale). Odontocetes include the Monodontidae (beluga ...

Flexi Disc
The flexi disc (also known as a phonosheet, Sonosheet or Soundsheet, a trademark) is a phonograph record made of a thin, flexible vinyl sheet with a molded-in spiral stylus groove, and is designed to be playable on a normal phonograph turntable. Flexible records were commercially introduced as the Eva-tone Soundsheet in 1962. They were very popular among children and teenagers and mass-produced by the state publisher in the Soviet government. History Before the advent of the compact disc, flexi discs were sometimes used as a means to include sound with printed material such as magazines and music instruction books. A flexi disc could be moulded with speech or music and bound into the text with a perforated seam, at very little cost and without any requirement for a hard binding. One problem with using the thinner vinyl was that the stylus's weight, combined with the flexi disc's low mass, would sometimes cause the disc to stop spinning on the turntable and become held in place b ...

Little Golden Records
Golden Records was a Simon & Schuster record label based in New York City. It was conceived and founded in 1948 by the Grammy Award-winning children's music producer, Arthur Shimkin, then a new recruit in the S&S business department. Shimkin went on to found Sesame Street Records with Children's Television Workshop in 1970. Golden was one of the first children's music labels to combine story with melody. It featured music to accompany Little Golden Books. However, they were not the first instance of a published series which combined books and records. This distinction goes to Bubble Books, published between 1917 and 1922. The label is mainly remembered for its children's music releases during the 1950s on a subsidiary label, Little Golden Records, which released singles rather than albums. As originally issued from 1948 to 1962, 78 r.p.m. Little Golden Records were six inches (15 cm) in diameter and made of bright yellow plastic (orange plastic was used for a few ti ...

Children's Gramophone Records
Children's music or kids' music is music composed and performed for children. In European-influenced contexts this means music, usually songs, written specifically for a juvenile audience. The composers are usually adults. Children's music has historically held both entertainment and educational functions. Children's music is often designed to provide an entertaining means of teaching children about their culture, other cultures, good behavior, facts and skills. Many are folk songs, but there is a whole genre of educational music that has become increasingly popular. History Early published music The growth of the popular music publishing industry, associated with New York's Tin Pan Alley in the late 19th and early 20th centuries led to the creation of a number of songs aimed at children. These included 'Ten little fingers and ten little toes' by Ira Shuster and Edward G. Nelson and ' School Days' (1907) by Gus Edwards and Will Cobb . Perhaps the best remembered now is " Teddy ...
