I've got all the PT albums and SW's solo stuff
His solo stuff isn't all that different from PT - maybe a bit self-indulgent and over the top at times, but still really good stuff. He has a new album (a mini album of finished ideas that were left off previous albums) coming out next week.
Sounds like he'll be playing some stuff from that plus the last album in full and some older stuff, so it should be a good show
Seen him live once before and he was really good.
