Information for Quadrophenia, a Mod Ballet at Sadler's Wells Theatre, Inner London (Dance or ballet). In 1973, guitar smashing rock genius Pete Townshend wrote QUADROPHENIA. Recorded by The Who - it quickly became an iconic and multi-million selling album. Quadrophenia defined a generation and in 1979 inspired the cult classic feature film of the same name. Sharp suits, soul music, vespas and parkas but its themes of lost youth, rebellion, the search for belonging and hunger for social change are just as urgent today.
