They came through San Diego 2X for the "35 Year Anniversary Tour." First time through took my family and after the concert I got Steve Howe's autograph on the program.
Second time through at the end of the tour almost 6 months later, bought two tickets to the concert, got the latest CD set, and a forth coming DVD called "Songs from Tsongas" and extended our PBS membership all at the same time. Great concerts. They just keep getting better and better believe it or not. They are incredibly tight, on, and smooth.
Went to the concert with a friend who has his own band and I respect his opinion musically, he knows so much about it all, and he hadn't seen YES since "Relayer" tour in the early 70's. He was blown away! That night after the concert, he couldn't wait, he got home and ordered many of their CDs and latest works. Next time they come to town you should go. By the way, Wakeman is back in the band. Also they have a recent DVD out with just acoustic versions of some classics, believe it or not, that concert was satellite "live" fed from LA to many movie theaters last year throughout the US as a special concert. Went to that with my daughter. Pretty neat experience. They're doing great.
