Jason Adasiewicz (born October 14, 1977) is an American jazz vibraphonist and composer.
Jason was born in Wichita, Kansas in 1977, but raised in Crystal Lake, Illinois. He studied jazz drums at DePaul University for three years.
Adasiewicz began playing the vibraphone after leaving school, first in the indie-rock scene around Chicago with bands like Pinetop Seven and the singer-songwriter Edith Frost.
In the early-2000s, Adasiewicz began his collaboration with cornetist Josh Berman and drummer Mike Reed. Since then he was worked in the Chicago jazz and improvisation scene with multiple bands, including Rob MazurekâÂÂs Starlicker and Exploding Star Orchestra, Mike ReedâÂÂs Loose Assembly, Josh Berman and His Gang, Nicole MitchellâÂÂs Ice Crystal, James FalzoneâÂÂs Klang and Ken VandermarkâÂÂs Topology and Audio One.
Adasiewicz formed his Chicago-based jazz quintet, Rolldown, in 2004, while living in Madison. In 2008 he founded the trio Sun Rooms, with Nate McBride and Mike Reed.
In 2017, Adasiewicz composed his first original film score, for Roy's World: Barry Gifford's Chicago. It was released as an album in 2023 by Corbett vs. Dempsey. All About Jazz commented: "It is wildly, deliriously entertaining and so dynamic, beautiful and fun that you'll want to play it over and over again."
