Closing out the Acura Stage on the final day of the New Orleans Jazz and Heritage Festival has become something of a tradition for Troy “Trombone Shorty” Andrews. And now he seems to have established another one the same week.

For the second year in a row, Andrews, New Orleans’ latest breakout star, and his shape-shifting rock/funk band Orleans Avenue will headline the Saenger Theatre during the busy Jazz Fest week. His 2016 “Treme Threauxdown,” as the hometown show is called, is April 23, the first Saturday of the festival.

The Dirty Dozen Brass Band is also on the bill. It’s entirely likely that additional musicians may join the roster.

Following a presale on Thursday, tickets for the “Treme Threauxdown” go on sale to the general public Friday at 10 a.m. via Ticketmaster, at LiveNation.com and at the Saenger box office. Tickets are priced at $50 or $150, plus service charges.

The 2015 “Threauxdown” came within a few dozen tickets of selling out the Saenger.

The Trombone Shorty show is being promoted by Live Nation Entertainment. Live Nation also is bringing singer-songwriter Ray LaMontagne to Bold Sphere Music at Champions Square on July 31. Following a presale for fans who pre-ordered LaMontagne’s forthcoming, sixth studio album, “Ouroboros,” via Amazon, tickets will go on sale to the general public March 4.

“Ouroboros,” due March 4 from RCA Records, was co-produced by My Morning Jacket frontman Jim James. The first single, “Hey, No Pressure,” hinted at the direction LaMontagne is headed with his new music.

His 2010 album “God Willin’ & the Creek Don’t Rise” won a Grammy Award as best folk album; his song “Beg Steal or Borrow” was nominated for song of the year.

His New Orleans show downtown at Champions Square is part of a summer-long 45-date tour in support of “Ouroboros.”
