A couple of members of the Paul Butterfield Blue Band went on to have very successful solo careers: Mike Bloomfield and Dave Sanborn.
If you are not familiar with Roy, do yourself a favor and give this live version of "Can I Change My Mind" a listen:

Some sweet stuff from the Pat Metheny Group back in the late 70's:

Saw Metheny and Lyle Mays on Boston Common.... years ago there was a summer program "Concerts on the Common" that had some great acts come through. Saw Santana there also.Not a huge fan of progressive jazz but I've always liked the group. Maybe a year ago they lost their keyboard Kyle May. The musicians of my younger days just seem to falling by the wayside. Saw them several times on Austin City Limits. Anyway, .
Cheers
Bill Payne on piano is a treat.
