In life there are certain truths: What goes up must come down, all's fair in love and war, a stitch in time saves nine and one who makes a synthesizer out of a cougar pelt is wicked awesome. Musician, teacher and installation artist Raven Chacon is familiar with the latter, having made just that as part of a Winnipeg-based project by his interdisciplinary American Indian arts collective, Postcommodity. When the piece is pet, the pelt synth purrs, and when it’s twisted it raars. The group also fashioned an antler cello and antler harp, and made a drum from a boar bladder and a coffee can. The instruments, says Chacon, are meant to be played by a futuristic tribe representing the last of its culture.
