Count on the MarchFourth Marching Band brigade (10:45 a.m., Preservation Hall) to ring in Halloween in true costumed pomp and performance. Add the season-appropriately named Walter "Wolfman" Washington & the Roadmasters (12:45 p.m., Soco/WWOZ) for some spooky blues-funk.
Janelle Monae , the Prince-ly, outer-space James Brown (2:15 p.m. Soco/WWOZ) performs concurrently with Minus the Bear (2:15 p.m., Voodoo), the noodley, "college dude" indie rockers.
Interpol (4:15 p.m., Voodoo), the long-running New York post-punk nü-Joy Division, meets New York's new class: the blog- and blotter-friendly MGMT (5:30 p.m., Sony), who've planted millions of earworms with the ubiquitous fauxhemian anthem "Time to Pretend":
Reigning bounce queens Big Freedia, Sissy Nobby, Katey Red and DJ Rusty Lazer take over the Bingo! Tent (6 p.m.) before they pass the baton to the tent's namesake and closing performers.
Fest closing duties go to My Morning Jacket, fresh from a marathon performance at Terminal 5, where the group performed its entire catalog over a string of dates. DJ Soul Sister's (8:30 p.m., Preservation Hall) cold funk jams kick off the afterparties.
Stay tuned to Gambit for a fest wrap-up, and have a happy Halloween.
