Pete Townshend was still in his twenties when he began plotting out the Who's follow-up to Who's Next, but he already felt like a relic of another era. The Who had been around for a decade, which for a rock band felt like an eternity. His mind turned back towards the band's early days playing wild sets to hordes of mods hopped up on pills. He decided to write another rock opera, this time about a young Who fan named Jimmy battling with girls, his parents, his friends and even his own mind.
Touching on real-life incidents – like the Brighton Beach brawl between mods and rockers – the double album Quadrophenia was a worthy follow-up to Tommy, though this time, kids all around the world related to Jimmy and his intense feelings of isolation. It proved too difficult to play onstage in 1973, but they revived it in 1996 and 2012 to much acclaim.
