What Jonathan Lethem is working on

"I've just finished a short and deliberately foolish novel called You Don't Love Me Yet, set in Los Angeles in the (approximately) early nineties, about discombobulated twenty-somethings in Echo Park who form a band and then accidentally steal the lyrics to their only good song. Which isn't a hit, anyway. Doubleday will publish it in March 2007. I was wondering about what it would be like if Iris Murdoch wrote a novel about indie rock, but the book didn't end up as deep as Iris Murdoch. I only hope it's both funny and sexy, because otherwise it has no excuse for being. Please think of it as a brave foray to retrieve irrelevance for American novel-writing."
