Imagine a musical instrument with one hundred wires strung over fifty feet. This is the extraordinary Long String Instrument (LSI), developed over twenty years by internationally acclaimed composer-performer Ellen Fullman. For this marquee event in Western Front's "String Theory" series, Fullman performed a selection of mesmerizing works on this unparalleled instrument. She was joined by master improviser-composer Brett Larner and an ensemble of seven guitarists plucking, fretting, bowing and hammering steel strings for Larner's hauntingly delicate composition "m-7/21-1".
