Which punk band's 1979 album 'Entertainment!' is a post-punk classic?

The punk band whose 1979 album 'Entertainment!' became a post-punk classic was Gang of Four.

Entertainment! was the English band's debut album, released in September 1979 by EMI in the UK and Warner Bros. in North America. It expanded punk's stripped-down attack with sharply interlocking guitar, prominent bass, funk rhythms, reggae and dub influences, and politically charged lyrics.

The core lineup consisted of singer Jon King, guitarist Andy Gill, bassist Dave Allen, and drummer Hugo Burnham. The album's songs examine consumerism, class, work, politics, and personal relationships, often using deliberately tense rhythms rather than conventional rock grooves. Its cover and presentation also reinforced the band's interest in media, power, and propaganda.

The album is sometimes grouped with records by Joy Division, Wire, or Public Image Ltd. because all helped shape post-punk. However, Entertainment! is specifically Gang of Four's debut, and tracks such as 'Damaged Goods,' 'At Home He's a Tourist,' and 'Anthrax' became central reference points for later alternative and dance-rock musicians.
