Klimchak is a composer known for his use of electronics & homebuilt instruments. His work has been seen in dance, theater & solo performances around the world. In 2011, he was given a grant by Idea Capital to make a series of compositions for home-built percussion instruments with lights incorporated in them. They were performed in 2012/2013 as flash percussion performances, titled Klimchak’s Lebeato Lounge. In March, 2015, Klimchak premiered his solo show, CooksNotes, in which he makes music on kitchen implements while cooking dinner for the audience.
Klimchak regularly performs solo shows featuring the Don Buchla designed Marimba Lumina. Only about 100 of this very rare instrument were made. With the Marimba Lumina the percussionist is able to perform live music that would normally take at least 4 musicians. His multi-instrumental compositions are played with 4 separate mallets, six foot pedals and a breath controller. As added touches, his sets usually include 4 or 5 small percussion instruments, some chanting or tuvan throat singing and at least one solo on the theremin.
