Kai Killion & The Getaway Dogs began as a thematic concept for the young singer-songwriter. On his debut full-length album, last year’s Mermaid Legs & Getaway Dogs, Killion deftly combines Brazilian soul and indie rock-folk for a hypnotically rhythmic and melodic collection of laid-back, though no less intriguing, acoustic tunes. The Getaway Dogs currently act as the back-up band for Killion’s live outfit, an ever-evolving lineup of close friends and collaborators from Killion’s hometown of Santa Cruz. This week, Kai Killion brings the Getaway Dogs with him when they play a post-holiday show on Friday, Dec. 26, at the Sleeping Lady, 23 Broadway, Fairfax. 9:30pm. 415.485.1182.
