Things look really iffy in the Aerosmith camp. Last weekend, after the troubled band wrapped its show for 50,000 fans at the Abu Dhabi Grand Prix, Steven Tyler suggested he was moving ahead with a solo career as his bandmates pondered a future without him.

"I don't know what I'm doing yet, but it's definitely going to be something Steven Tyler: working on the brand of myself -- Brand Tyler," the frontman told Classic Rock magazine. While there was no indication of acrimony onstage, reportedly just smiles and agreeable banter, the quintet's internal politics seem destined to grind the Boston rock institution to a halt just short of its 40th anniversary next year.

Things have been strained since the group's US Summer tour with ZZ Top came to an end when Tyler fell off a stage in Sturgis, S.D. Meanwhile, guitarist Joe Perry's frustrated Tweets aggravated matters, prompting the singer to pull out of a South American tour planned for late 2009. During the band's three recent shows, Tyler stayed away from the rest of Aerosmith until the opening number.

Now the band intends to reconvene in the near future to discuss its next steps, sans Tyler. With the legendary frontman seriously considering an exit, Aerosmith will either announce a long hiatus or decide to move forward with a new lead singer.

"I'm not sure how good that would look, it would largely depend on who we could get and who would want to do it," Brad Whitford told the magazine's website. "That's big shoes to fill. Nobody could replace Steven or imitate him -- he's one of a kind. But if somebody was willing to do it and the chemistry was right, why not?"
