Just... listen to Who's next as a whole. Them Tommy as a whole. Then Quadrophenia (but Who's next first, remember). Fucking amazing band right there, definetely in my top 5.
The way Keith Moon uses drums as more than a simple tool for keeping rythtm (Baba O'Riley, Won't get fooled again), John Entwhistle's incredible, incredible bass (the Real me, for example, or the bass line on Pinball Wizard), the incredible composing skills of Townshend (he wrote the entire Tommy album, and all of the others... props), and Daltrey's voice on Who's next is probably one of the most well-balanced; not over the top like Plant or Geddy Lee, but very powerful.
