i liked Yes, but I have a feeling they'd be pretty boring in concert. Never saw them live, but they seem like they would be.
Here is an interesting topic: Good and bad concerts you have seen
A few of the worst:
Van Morrison, Moody Blues, Pure Prairie League, Brockhampton ( a rap group I took my two sons to see)
A few of the best:
John Hiatt, Peter Gabriel, Brandi Carlisle, Jethro Tull, Billy Joel, Deep Purple, David Bowie, Cowboy Junkies, Richard Thompson
