...And Then There Were Three...

...And Then There Were Three... (stylised in all lowercase) is the ninth studio album by English rock band Genesis. It was released on 31 March 1978 by Charisma Records in the UK and by Atlantic Records in the US. The album marks a major turning point in the band's history, following the departure of guitarist Steve Hackett. This reduced the line-up to a core trio of drummer and vocalist Phil Collins, keyboardist Tony Banks, and bassist/guitarist Mike Rutherford. Faced with the loss of a primary songwriter, the remaining members deliberately shifted away from the sprawling, epic progressive rock structures that defined their previous work, opting instead for shorter, tighter, and more direct song formats.

The album was recorded in the Netherlands and mixed at Trident Studios in London, under the direction of the band and producer David Hentschel. With Hackett gone, Rutherford took on all studio guitar duties, which significantly simplified the group's arrangements. The new songwriting approach yielded the band's first major global hit single, "Follow You Follow Me", which became their highest charting at that point, reaching No. 7 in the UK and No. 23 in the US. The single broadened their demographic appeal and helped bridge the gap between their traditional fan base and mainstream pop audiences.

Upon release, ...And Then There Were Three... received mixed reviews from critics. Traditionalists lamented the loss of complex progressive textures, while others praised the group's newfound pop accessibility. Despite the critical divide, the album achieved substantial commercial success, peaking at No. 3 in the UK and became the band's highest-charting album in the US at the time, reaching No. 14 and earning a platinum certification for selling one million copies. The subsequent 1978 world tour was their first with live guitarist Daryl Stuermer, and cemented their status as a major arena act, establishing the commercial blueprint that would define their massive stadium success throughout the 1980s. The album was reissued in 2007 with a new stereo and 5.1 surround sound mix and bonus material as part of the Genesis 1976–1982 box set.
