The Upsetters were producer Lee ‘Scratch’ Perry’s studio band.
There were actually two Upsetter line-ups. The original band, lead by pianist Gladstone ‘Gladdy’ Anderson, recorded the essential ska ditty Return Of Django. When Gladdy and his boys couldn’t travel to the UK for a tour, Perry assembled another Upsetters group.
The new band included brothers Aston ‘Family Man’ Barrett on bass and drummer Carlton Barrett. These guys would eventually form the backbone of Bob Marley’s backing band, The Wailers.
U is also for… The Untouchables: Formed in Los Angeles in 1981, The Untouchables broke through in the UK with the Two-Tone style stomper Free Yourself. The band has had more ‘former members’ than Spinal Tap and are still on the go apparently.
