A pianist and accordion player, he has taught the latter at Klezfest London, where he has also run workshops in "hiphopkele". He has played with clarinetist David Krakauer's Klezmer Madness!, and has also worked with artists such as rapper C-Rayz Walz, Chilly Gonzales, funk trombonist Fred Wesley, and Sophie Solomon.
