Dumpstaphunk will return to Sweetwater Music Hall tonight for their annual Halloween celebration in Mill Valley, CA. For the second year in a row, Grateful Dead guitarist Bob Weir will join the New Orleans funk masters for a night of mischief music, alongside the Jazz Mafia Horns. In 2016, Weir joined Dumpstaphunk for a “Shakedown Street >Dear Prudence > Iko Iko > Big Chief New Orleans Medley > Knockin’ on Heavens Door” medley that kept fans dancing all night long. There’s no telling what will go down tonight, but the band warns fans to come on out and “find out what tricks n treats we gonna pull outta the Dumpsta!!”

There is a limited supply of tickets left here.

Check out a taste of what’s to come in the video below, from last year’s “Shakedown Street”:
