Bands usually swim straight down the shitter after losing their most talented members, but not Little Feat. Although the group fell apart when founder Lowell George cut and run in 1979 (he died that same year), the Feats reformed nine years later. At first, the band enlisted Pure Prairie League's Craig Fuller and tried to write hit tunes and record studio albums, just as it did a decade earlier. But they soon realized there was no replacing a visionary like George. Wisely, Little Feat totally reinvented itself. Nowadays, they are one of the jam band scene's best outfits, right up there with Widespread Panic. That's because the Feats are grounded in classic 1970s rock, not the hippie-frat funk of bands like Phish, O.A.R. and moe. Thank Jesus for that. Moore Theatre, 1932 Second Ave., 443-1744. 8 p.m., $30.50-$40.50. All ages.
