Great Overall Career Arc -- Group/Solo

I'm interested in opinions on great artist who started out in a great band(s) and then went on to have equally great or better solo careers. The starting band can be relatively short-lived (at least 2 albums), but the solo career should be long-lived, or vice versa.

An obvious example would be John Lennon, but after thinking about it I don't think he qualifies. Is his solo work really as good or better than his original group work? I think the same applies to Brian Wilson, Smokey Robinson, Eric Clapton, Phil Collins, George Clinton or Sting.

I'm thinking more along the lines of Neil Young (Buffalo Springfield), Bryan Ferry (Roxy Music), Gram Parsons (Byrds & Flying Burrito Bros.), Jeff Beck (Yardbirds), Micheal Jackson (Jackson 5), Dave Alvin (Blasters) or even Robin Trower (Procol Harum).

Who would you include on this list?
