My wife, son, and I just returned from our first music festival. Bonnaroo 2011 (aka Dustaroo 2011) sported rather oppressive conditions during daylight hours with a thick swirling layer of dust. Once dusk finally arrived however, Bonnaroo was magical. Although the feel of the experience was literally night and day, the music was excellent around the clock.
We (or I) took in the following sets or parts of sets:
My Morning Jacket
Portugal. The Man
The Black Keys
