If you haven't yet scored tickets for the Monolith Festival, which is just over a week off, now might be the ideal time to get them and save a few bucks. Esurance, one of the festivals sponsors, just released a block of 400 $99 two-day passes (no service fees) that are only available for the next 48 hours. Yeah Yeah Yeahs, Of Montreal, Girl Talk, Dandy Warhols and Phoenix are just a few of the stellar acts that will be at Red Rocks Saturday and Sunday, September 12 and 13.
