The celebration will take the form of a New Year’s Eve gala at Tipitina’s, a New Orleans landmark and a longtime haunt of the band. The band promises the show will feature many special guests and two full sets, in “classic Galactic fashion.”

A $3 surcharge on tickets will benefit the Tipitina’s Foundation, a charity dedicated to preserving the culture of the hurricane-ravaged city.

The band’s birthday bash was originally scheduled for early September.

Prior to the New Year’s gig, Galactic will finish off its 10-Year Invasion Fall Tour with two shows at Washington, D.C.’s 9:30 Club. The shows will be a “New Orleans style party,” according to the band, with guest appearances from Ivan Neville, The Stooges Brass Band and more.
