On Saturday, September 22, Shamarr Allen will celebrate the release of his new album with a party and an appearance from a very special guest.

At the House of Blues, the trumpeter, vocalist and songwriter will be joined by Big Freedia to celebrate True Orleans, his first album since going viral earlier this year with “Hit the Sean Payton.”

In July, Allen spoke with OffBeat.com about True Orleans. “To me, True Orleans is everything about New Orleans that’s really New Orleans, like real, genuine, organic New Orleans,” Allen said. “So I decided to release this video first to show that this whole CD is just based on fun and having a good time and great energy. It’s a whole album of feel-good music.”

September 22’s release party at the House of Blues is 18+ and doors open at 8 p.m. Pre-sale tickets are available here; general on-sale begins Friday, August 17, at 10 a.m.
