How do you play an instrument you never physically touch? Watch Carolina Eyck. She's the first to bring a theremin to the Tiny Desk. The early electronic instrument with the slithery sound was invented almost 100 years ago by Leon Theremin, a Soviet scientist with a penchant for espionage. It looks like a simple black metal box with a couple of protruding antennae, but to play the theremin like Eyck does, with her lyrical phrasing and precisely "fingered" articulation, takes a special kind of virtuosity.

"I'm really playing air," she tells the Tiny Desk audience. "I don't touch anything while I play." The position of the hands influences electromagnetic fields to produce pitch and volume. Recognized as one of today's preeminent theremin specialists, Eyck writes her own compositions, such as the pulsating "Delphic" which opens the set, and she's got big shot composers writing theremin concertos for her.

Joining Eyck for this two-musician-in-one Tiny Desk is cellist Clarice Jensen. When she's not making gorgeous, drone-infused albums like last year's For This From That Will be Filled, Jensen directs one of today's leading new music outfits, ACME, the American Contemporary Music Ensemble. "Three Leos," composed by Jensen, offers her masterful art of looping the cello into symphonic layers of swirling, submerged choirs with a wistful tune soaring above.

The two musicians close with "Frequencies," a piece jointly composed specifically for this Tiny Desk performance. Amid roiling figures in cello and melodies hovering in the theremin, listen closely for a wink at the NPR Morning Edition theme music.
