The sweet emotions that the members of Aerosmith once felt towards each other have apparently come to an end. In an interview with The Las Vegas Sun, the group's lead guitarist, Joe Perry, said that the singer Steven Tyler quit after a concert in Abu Dhabi. "Steven quit as far as I can tell," Mr. Perry told The Sun. "I don't know any more than you do about it."

Mr. Perry was responding to remarks that Mr. Tyler made in an interview with Classic Rock, a British music magazine, in which Mr. Tyler said that he was preparing to focus on a solo career. "I don't know what I'm doing yet," Mr. Tyler said, "but it's definitely going to be something Steven Tyler: working on the brand of myself - Brand Tyler." Mr. Perry said he had had difficulty confirming this with Mr. Tyler because the singer doesn't return his phone calls. "He's notorious for that," Mr. Perry told The Sun. "That's one thing I've learned to live with. I try to overlook it."

Aerosmith canceled several concerts over the summer amid an injury-plagued season after Mr. Tyler fell from a stage on Aug. 5. A publicist for the band did not immediately return a request for comment.
