Ume Roger Daltrey and Pete Towshend on the "Quadrophenia and More" tour.
The Who: Quadrophenia Live in London
Universal CD/DVD, various formats and prices
While it is not their most famous rock opera -- that would be the one with a certain deaf, dumb and blind boy, Pinball Wizard, Acid Queen and good ol' Uncle Ernie -- the Who's Quadrophenia is in many ways the superior work.
In an nutshell, the 1973 double LP told the story of Jimmy, a teen living in mid-'60s London, as he deals with his peers, parents, girlfriend, Mod lifestyle, the cusp of manhood, disillusionment, possible suicide and his future all while suffering from a form of schizophrenia. Composer Pete Townshend imbues Jimmy's condition with personality traits from all four members of the Who, thus the "quadrophenia" of the title.
