Here's some video of Atmosphere performing at Bonnaroo couple weeks ago. Atmosphere often gets mid-to-late afternoon time slots at big music festivals, but seem to always draw a huge crowd. I had a friend who went to Bonnaroo this year and he told me that Atmosphere tore it down. Hit this link to view a few more videos from their set. Atmosphere is on the road right now and you can also catch them in a festival setting at Lollapalooza in August.
