GALACTIC, THE DEPOT, Monday, March 10, 8 p.m., $21 advance/$26 day of show

New Orleans funk and soul crew Galactic have undergone an incredible amount of evolutions over their career, working through a variety of lead vocalists--on the songs that need voices--while remaining consistently engaging. In a live setting, it's easy to understand why the band has managed to grow its audience at a slow but steady pace through the years--they have an ace group of musicians capable of jamming out to improvisational nirvana, or locking into tight grooves and shifting moods, collectively, on a dime. The albums, like many awesome live acts, are a bit more spotty, but even Galactic's recorded work has gotten better later in their existence. Their most recent release, Carnivale Electricos, is an excellent collection of Mardi Gras-inspired fare. On the band's current tour, Maggie Koerner is joining the fun; she's featured on the band's new single, "Dolla  Diva." Brushy One String opens the show Monday.
