From Mod-era "maximum R&B" to rock operas and quintessential Seventies hard rock, the Who reigned across the decades as one of the greatest rock and roll bands of all time. At their best, they distilled the pent-up energy and chaos of rock and roll into its purest form while investing their music with literary wiles and visionary insight. In their prime they were a unit whose individual personalities fused into a larger-than-life whole. Pete Townshend provided the slashing guitar work and much of the material. Vocalist Roger Daltrey injected the songs with expressive muscularity and passion. Bassist John Entwistle anchored the band with his stoic demeanor and expert musicianship. Keith Moon, one of the greatest of all rock and roll drummers, embodied their explosive energy and anarchic wit.
