Experimental-improv artist Eli Smith released a new composition recently. Spanning over a half hour long, this piece utilizes no digital elements and instead favors entirely acoustic instruments and objects. Among the sonic tools Smith uses here are singing bowls, a violin bow, a thunder tube, a cymbal with water poured on it, chimes and bells. As shrill tones beam in and out, Smith conducts vibrations ranging from storm-like rumbling to ominously trickling liquid to repetitious tapping of bowls with “Emptying Vessel.”
