The crowds will pour out from the New Orleans Jazz & Heritage Festival grounds, and they have to go somewhere. Or everywhere. Clubs compete in every neighborhood, foot traffic increases, One Eyed Jacks retires rock 'n' roll (at least for a couple weeks), and you get the idea it's music overload, and you aren't trying if you can't find something to do for the next two weekends.
Seguenon Kone performs a free show at 3 Ring Circus' Big Top Gallery (8 p.m.); Sharon Jones & the Dap-Kings headlines, with appropriate openers Dumpstaphunk, at Howlin' Wolf (10 p.m.); Guitar Lightnin' Lee does Saturn Bar (10 p.m.); Caddywhompus headlines its album release for the spectacular Remainder (which you can download for free starting May 11) at Ernie K. Doe's Mother-In-Law Lounge (9 p.m.); Dirty Dozen Brass Band performs My Feet Can't Fail Me Now in its entirety at One Eyed Jacks (9 p.m.); George Porter Jr. & his Runnin' Pardners hits Tipitina's French Quarter venue at an unholy hour (2 a.m.); for early birds, Hurray for the Riff Raff plays down da road from the festival grounds at Domino Sound Record Shack (7 p.m.); and King Rey does Circle Bar (10 p.m.).
Morning 40 Federation comes back to earth at One Eyed Jacks (10 p.m.); Rebirth Brass Band is with Joe Krown and Walter "Wolfman" Washington at Howlin' Wolf (10 p.m.); Patti Smith brings punk rock to Tipitina's Uptown (10 p.m.), absent since Fugazi (2002), while Anders Osborne is at the venue's Quarter equivalent (10 p.m.); and DJs Kristen and Matty rule as Emperors of the Youth at the inevitably sweaty rain-refuge Mod Dance Party at Saturn Bar (11 p.m.).
If you're not watching Treme, for some reason, there is the New Orleans Klezmer Allstars at the Den at Howlin' Wolf (10 p.m.) and a free metal show at The Saint: The Anselmo-approved, heavy, heavy Haarp, with Mountain of Wizard and The Unbeheld (8 p.m.), followed by DJ Pasta.
