Attack of the Mutant Theremin with Kip Rosser
Observatory (543 Union St., Brooklyn)

Thereminist Kip Rosser will demonstrate why Halloween is the perfect time of year for a scholarly and irreverent evening of bizarre history and strange science, featuring live music played on the weirdest instrument on the planet. The theremin was the world’s first electronic instrument, the first amplified instrument, and the original synthesizer. Today, it remains the only instrument ever invented that’s played without being touched.
