Quadrophenia (1973)

Pete Townshend's second rock opera follows Jimmy, a young mod in 1960s London whose split personality the record gives four musical themes, one for each member of The Who. Listen for those themes returning across the four sides, thickened with horns and synthesisers. The Real Me opens with John Entwistle's bass at full tilt; Love, Reign o'er Me shows where all the themes were heading.
