Aliana premieres new music by David Coll on “Not-So-Heavy Metals,” which features transducers and sheet metals in a display of sonic playfulness, melding sound processing with live instruments. Composers and sound artists David Coll and Patricia Alessandrini will display their technical wizardry, complemented by several short works by MIT Composition Seminar students. And to complete this sonic adventure, we present a brand new work by MIT’s MLK Visiting Scholar Matthew Schumaker, specially commissioned for the 2019 Cambridge Science Festival.
