And SXSW keeps getting weirder and weirder. Before their set yesterday afternoon, Nashville 6-piece Diarrhea Planet took to the stage with raspy rock goddess Melissa Etheridge and Austin's The Midgetmen for a rousing cover of Tom Petty's “Refugee.” There have never been so many guitars in one place. Most bewildering, however, is DP's drummer Casey not on the skins but shredding on the axe? SXSW, you are crazy.
