I've got tix for both days, but messed up my back at tennis yesterday so waiting to see how much I can handle. Them claiming to bring back the full festival complete with weird arts acts, but treating it as any other music festival with no re-entry, is egregiously dumb.
Aside from the ones you mentioned - Warpaint, Girl Trouble, Rebirth Brass Band & The Black Tones mostly overlap but are both worth seeing, Beverly Crusher, Spirit Award, *Descendents* (and not just because Milo had a heart attack last month)
