The Longwave is a longitudinal friction harp invented by Ela Lamblin with choreography by Leah Mann. It is played by stroking the long strings with rosin coated gloves. While this is not the first instrument to utilize the longitudinal mode of vibration (the cuica, and Ellen Fullman's long string instrument are two other examples), Ela innovated the use of rosin gloves, of wooden tuning blocks, and was the first to arrange strings in a harp-like fashion. Like all of lelavision's work, the Longwave exemplifies the performance of music and choreography in simultaneity. Visit lelavision.com for more info.
The Pandemonium is a boat-like musical-sculpture created by Ela Lamblin with choreography by Leah Mann. The instrument portion is in the middle and serves as the boats motor. It is a balloon reed organ made entirely from plumbing parts and balloons. It plays via a keyboard made from garden hose spray nozzles. The air pressure for the instrument comes from the large balloons on the sides and top deflating. They are re-inflated by pumping bellows made from large toilet plungers located in the center of the vessel. In addition, the performers (Leah and Ela) use small balloon reed devices in their mouths to make the voice like honks and squawks.
