The crowds at everything but M83 were awesome since the Sahara was packed all day long. We were able to walk to the front of Pulp, Refused, Mazzy Star, Atari Teenage Riot, Explosions in the Sky, and EMA without difficulty. All of the stages are generally half-packed or less. The "band" crowds seem to be skewed towards the older attendees, so it's a very segregated experience.
