Their recent reunion album was quite good. I love Bruce. I think he was one of the greatest singers of classic rock besides one of the best bass players, and I love him on the Michael Mantler stuff too. I recently watched a documentary about the Cream reunion. I was unaware of how much Ginger Baker can't stand Bruce!
The success of Cream is quite surprising given how much the 3 of them couldn't stand one another. If you read Clapton's autobiography (a good read, btw), you'll find out how bummed out Clapton was that Winwood wanted Baker for Blind Faith. I agree on Bruce. However, I revisited "Songs for a Tailor" and "Harmony Row" today, and found them both to be quite pedestrian.
Ouch! "Harmony Row" is one of my favorite albums.
I highly recommend Kip Hanrahan's Vertical's Currency (with Jack on the cover) for a different take on his talent - both instrumentally and vocally. Check out Jack's work on the sensual "Make Love 2" and also a version of "Smiles & Grins" from Harmony Row.
