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?

I agree that Alejandro Escovedo (and all of the bands he's played with) have flown well below the radar. I guess he had his 15 minutes when Springsteen jumped on his bandwagon, but there's no question we're not talking household name here.

OTOH, I also think that the music has (pretty) consistently been great and, often, astonishing. He's one of those rare beasts with both a right brain rocker gift and a left brain songwriter gift. I'd put his career output up against anyone listed here, but that is certainly reflective of my personal taste.

Tom Petty - "Mudcrutch?" , then TP&the heartbreakers, then solo, then back. Does he qualify?
Emmylou Harris. Two albums with Gram Parsons then an outstanding solo career marked by grace, humor, integrity and great music.
