"Abacab" is the eleventh studio album by English rock band Genesis, released on 18 September 1981 in the United Kingdom by Charisma Records and 24 September 1981 in the United States by Atlantic Records. After their 1980 tour in support of their previous album Duke, the band took a break before they reconvened in 1981 to write and record a new album. Abacab is the first Genesis album recorded at The Farm, a recording studio bought by the group in Chiddingfold, Surrey. It marked the band's development from their progressive roots into more accessible and pop-oriented songs, and their conscious decision to write songs unlike their previous albums. "Abacab" received a mostly positive reception from critics and was a commercial success for the band, reaching #1 on the UK Albums Chart and #7 on the US Billboard 200.
