Icelu was first formed by four students at Lawrence University in Appleton, Wisconsin in 2004. After graduation, icelu parted ways for one year before converging on Brooklyn, where they are now based. Icelu has always been based on the idea that collaboration with other artists is much more successful than working alone. Dedicated solely to new music, icelu strives to stretch boundaries by working with dancers, film makers, visual artists, writers, and all other artists.

Icelu is Jonathon Roberts, voice and keyboard; Ben Klein, tuba; Reid Stratton, euphonium; and Bryan Teoh, guitar and laptop.
