IO (eye-oh) is a violent and beautiful moon of Jupiter. It's also a great band from SF. If you ever want to hear an extremely long and boring story just ask me how I came to know these guys. IO is currently a four piece, but the pictures don't seem to reflect that. Drummers tend to get lost in photography. White shirts in rear, dark shirts in front. I plan to delivery 'better' pictures as soon as I get another chance to shoot them. IO is volcanic. So is Jupiter's moon. Check'em out here: http://www.iorock.com
