Happy Mondays are an English rock band formed in Salford in 1980. The band’s original line-up was Shaun Ryder (vocals), his brother Paul Ryder (bass), Mark Day (guitar), Paul Davis (keyboard), and Gary Whelan (drums). Mark “Bez” Berry later joined the band onstage as a dancer/percussionist. Rowetta joined the band as a guest vocalist in 1990.
The group’s work bridged the Manchester independent rock music of the 1980s and the emerging UK rave scene, drawing influence from funk, house, and psychedelia to pioneer the Madchester sound. They experienced their commercial peak with the releases Bummed (1988), Madchester Rave On (1989), and Pills ‘n’ Thrills and Bellyaches (1990), with the latter going platinum in the UK. They disbanded in 1993, and have reformed several times in subsequent decades.
