Pushing the envelope

If Om makes you think about meditating, and Six Organs of Admittance conjures images of kidneys and livers, and Lichens sends you to the medicine cabinet, you have to update your music repertoire at “New Music Now: Om, Six Organs of Admittance, and Lichens.’’ This collaboration between the Institute of Contemporary Art and World Music/CRASHarts presents the cutting edge of indie rock, jazz, electronica, and other boundary-pushing artists. Pictured: Om. 8 p.m. $16. Institute of Contemporary Art, 100 Northern Ave., Boston. 617-876-4275. www.worldmusic.org
