To my ear, Deerhunter is the best new band I've heard in 2007. But at a recent New York show, I listened in disbelief as lead singer Bradford Cox held forth in a post-show monologue for over 20 minutes, covering his childhood and all sorts of other topics. The guitarist walked back onto the stage and whispered something to Cox, who then said something like "he says I should stop talking, and that I always do this, but I'm going to keep talking because..."
Most of the audience stood transfixed, listening, but I left. I thought the guitarist was right: it would have been a better idea to let the band's (excellent) music do the talking.
According to Pitchfork, a disagreement along those lines has lead to that guitarist, Colin Mee, leaving the band, citing media overexposure -- especially Cox's enthusiastic, confessional blogging style -- as a reason.
Update: Colin Mee rejoined Deerhunter.
I think my friend Craig said it best: "well, it was good while it lasted."
