“A Bookmobile for Dreamers,” a multimedia chamber opera for live theremin, electronic sound and video by Brooklyn composer Elizabeth Brown and artist Lothar Osterburg, will be performed Saturday, May 23, at 7:30 p.m. at Watts Hall, Main Street/Route 1.

Brown will play the theremin, an electronic instrument invented by Soviet scientist Leon Theremin. The performance is a fundraiser for the New Building Capital Campaign of the Pope Memorial Humane Society of Knox County that is well on its way to raising 2.2 million dollars to build a new, larger and more efficient animal shelter.

The piece originally was commissioned by the Electronic Music Foundation through Meet the Composer's Commissioning Music/USA program. A 40-minute performance inspired by the joy of browsing, “A Bookmobile for Dreamers” celebrates the imagination as inspired by the printed word. Brown and Osterburg created much of the piece while in residence at the Liguria Study Center in Bogliasco, Italy, in 2011. It has been performed numerous times in Europe and the United States.

Suggested donation for “A Bookmobile for Dreamers” is $10 at the door. Following the performance, there will be an opportunity to meet Brown and Osterburg and to experience what it is like to play a theremin. A preview of “A Bookmobile for Dreamers” is available on YouTube (see below). For more information on the Watts Hall event, call 594-4897 or visit hskcme.org.
