Sonic Swimming

After more than 20 years and almost as many albums, Yo La Tengo remain one of the most vibrant bands in indie rock. Few groups demonstrate as much range (from distorted, Sonic Youth-esque outbursts, to melodic, melancholy grooves), and even fewer take such a fearless approach to experimentation. Tonight, husband-and-wife Ira Kaplan and Georgia Hubley, and bassist James McNew, play tour guides on an underwater adventure, offering their live score "The Sounds of Science" to some of the tripped-out sea-life documentaries of Jean Painleve, who made over 200 short films before his death in 1989. Swim alongside seahorses and octopi, explore hidden reefs, and become transfixed by liquid crystals while floating atop Kaplan's lulling guitar lines and Hubley's shuddering cymbal work. Get there early for a short set by rising folk star Samara Lubelski, whose sparkling vocals and fluid melodies have a way of making you feel weightless too.
