Freelance photographer Ian Witlen was shooting for us at the Crystal Method show at Revolution last night when he spotted what he says was Joaquin Phoenix in the crowd. From the photo it looks like a unshaven guy in a top hat, so we aren't 100 percent convinced its him. However, Witlen says as soon as he shot "Phoenix" he got angry and left the area, so it might have been him (sure sounds like him). As you know, Phoenix was in South Florida recently -- Miami Beach be exact -- where he "performed" for 90 seconds before he pretended to get into a fight.
By the way, you can check out the full slideshow of the Crystal Method's performance last night here.
