When we say there's something for everyone at Perry Farrell's mammoth festival, we're not just paying lip service. If you can't find at least one act you like amidst the 100-plus on the bill, well, you might want to give up on music in general. The Strokes, Green Day, Lady Gaga and Soundgarden are among the "headliners," but you're just as likely to find your favorite band halfway down the list, playing a small stage in the afternoon. While you're exploring, make sure to drop by the Kidzapalooza area, where many a big name has played a set for the wee ones over the years.
