Eight years after making his light-tripping Drum Buddy the center of the wildest New Orleans Museum of Art exhibit anyone has ever seen (or heard), Quintron — spell-casting Willy Wonka of the 9th Ward — is back on official display. His latest Quintronics invention, the Weather Warlock, is wilder still and yet cosmically, comically Zen-like: an analog synthesizer "played" by weather-sensitive, PVC-mounted sensors, resulting in a never-ending major-chord drone riffed on by a mercurial free-jazz choir of sunshine, moonlight, rain, wind and the tiniest fluctuations in temperature or barometric pressure. Streaming day and night at the website www.weatherfortheblind.org, the instrument is temporarily stationed on the fifth floor terrace of the Ogden Museum of Southern Art, a living, breathing, burbling and gurgling contribution to the Prospect.4 international art triennial. Before that, the sensory medium took a trip to Abu Dhabi in the United Arab Emirates, where it served as a musical shrine prayed upon by its creator, backed by Eyehategod's Aaron Hill and a group of area musicians on oud (a Middle Eastern lute), mellotron and hand drums. In a stars-aligning scenario, those live sessions, captured on an album called Headless Falcon (Rhinestone), receive their release party here — a singing bowl touched by the gods in the dusk of the winter solstice, the long night from which all longer days are born. Tickets $13.50 (free for Ogden Museum members).
