I thought I would put in my two cents into this old, dusty thread. Not much is going on here, lately; this may generate some posts.
I respect what David does. He makes the music he loves, doesn't make too much money, and doesn't charge much for his shows. The feeling I got what that the Talking Heads would be given oodles of dough for a few gigs, but that's when I would draw the line. I'm glad David did. It's been many years since they were together making new music, and it wouldn't make sense for them to try it again twenty years later. If Paul, John, George, and Ringo got together a year before John was shot, the world would go ga-ga, but they couldn't make a real Beatles album. Then again, Primus just made a new album after ten years, and it sounds pretty good.
Chris, Tina, and Jerry have made their own music, and it's all very good (I'm not a huge fan of the poppier TTC stuff, though). If I were them, I would continue to make my good music, because they have a chance to make their own mark too.
As far as the band's reasons for breaking up... If David Byrne did it, I can't blame him. It didn't seem that they got along, he had other interests, and they seemed to have other interests too. What's the problem with breaking up? It is the money?
Just do what you love... Though, I think The Heads could have used Adrian Belew on vocals and guitar for some things...
