As you may already know if you followed Rocks Off's copious ACL coverage
, Austin's Zilker Park is a muddy ruin.
We use the term "muddy" loosely, as much of the turf churned into muck by dancing festival-goers was a substance called "Dillo Dirt," which is part recycled sewage. As a salute to the brown soup created by the City of Austin's efforts to go green, we've put together a slideshow of album covers featuring dirt, mud and, of course, poop. Enjoy!
