Forget about peace, love and understanding. Brothers in rock ‘n’ roll bands aren’t meant to get along. The unwritten rule stretches back to the Everly Brothers, whose siblings, Phil and Don, cemented their disdain for one another by breaking up on stage in 1973. Similar feuds between Liam and Noel Gallagher (Oasis), Ray and Dave Davies (Kinks), William and Jim Reid (The Jesus and Mary Chain) and Gary and Van Conner (Screaming Trees) have become as famous as their respective groups’ music.
