The Bobs

The Bobs were an American a cappella vocal group founded in San Francisco, California, in 1981. Often described as a "band without instruments," The Bobs were known for their irreverent humor, complex vocal arrangements, original compositions, and inventive covers.

Over a 36-year career, they released 16 albums, received a Grammy nomination for their a cappella version of "Helter Skelter," and performed worldwide before retiring in 2017.

They are regarded as pioneers in the modern a cappella movement, noted for their extensive original material and genre-defying performances.
