Today, we celebrate the birthday of New Orleans' foremost jazzman, Louis Armstrong with Satchmo Summer Fest at Old U.S. Mint. Elsewhere, White Linen Night steps out on Julia Street, the Lower 9th Ward Creative Arts Festival in Sam Bonart Park, and Ladies Arm Wrestling at One Eyed Jack’s. It's also the birthday of Frankie Ford (1939), and the day when Wynton Marsalis and Buckwheat Zydeco were among the performers at the closing ceremony of the 1996 Olympic Games in Atlanta. Now for today's full rundown:

Satchmo Summer Fest (Old U.S. Mint, 12:00pm-8:00pm) The annual celebration of Louis Armstrong’s birthday will feature two stages of live music, including Jesse McBride, Treme Brass Band, Yoshio Toyama & the Dixie Saints, Delfeayo Marsalis & The Uptown Jazz Orchestra, Big Chief Bo Dollis, Jr. and the Wild Magnolias, Stooges Brass Band and more. Between sets at the Cornet Chop Suey Stage, the Dancing Man 504, NOLA Jitterbugs and Dance Quarter will offer free dance lessons for all ages. The seminars are “My Friend Satchmo, Part II” with Stephen Maitland-Lewis at 2:00pm, “Digital Satchmo” with Richard Havers at 3:00pm, a 6-piece informance called “String Bands, Hawaii and Satchmo” at 4:00pm, and “Cinematic Satch” with Ricky Riccardi at 5:00pm.

Lower 9th Ward Creative Arts Festival (Sam Bonart Park, 1201 Forstall Street, 12:00pm-4:00pm) Hosted by Nicks International Community Foundation and Don’t Even Trip Dream Foundation, the festival includes live African/New Orleans music by Bamboula 2000, food, school supplies giveaway, free health screenings, voter registration drive, face painting, and arts & crafts. 

White Linen Night (Julia Street, CBD, 6:00pm-9:00pm) Don white linens as 21 museums and galleries open up their doors to guests for free. Live music on three stages by The Good Country Hey Brahs, Jim McCormick and Mark Carson, Picnic, and Jim Smith’s Damn Frontier.

NOLAW Arm Wrestling (One Eyed Jack’s, 8:00pm) Brawny babes battle over a little table for big glory. Women dress up in their alter egos to compete for a cause. $5 entry, proceeds go to Liberty’s Kitchen, which helps at-risk youth to develop employable skills. DJ Justin and Brian Boyles bring the dance party. Halftime acts of burlesque and trapeze by Trixie Minx, the Mystic Ponies and more.

White Linen After Party with Rebirth Brass Band (Howlin’ Wolf, 10:00pm) Local living legends of brass burst their necks to celebrate White Linen Night. The Grammy-winning band plays traditional New Orleans brass and heavy funk. $15. 

Dirty Projectors (House of Blues, 9 p.m.) This New York City band catapulted to noteriety on the back of 2009's Bitte Orca, a joyous, disjointed amalgamation of angular guitars, 3-woman harmonies and some of indie rock's funkiest beats. Now, the Dave Longstreth and co. are back with Swing Lo Magellan, a more subtle yet equally rewarding set of songs that utilizes roughly the same parts as Orca.

NOLA Theatre This weekend on the stage, the Urban Education Smackdown returns to the Shadowbox Theatre (8:00PM), and Waiting Around: The Restaurant Musical is at Allways Lounge (8:00 PM), while Fiddler on the Roof closes out the Tulane Summer Lyric Theatre season at Dixon Hall (8:00 PM)
