Dr.Asperger's Klezmer Tonic was formed early in 2002 by musicians/composers Rohan Kriwaczek and Nik Ammar as a result of a mutual desire to break away from purely traditional Sephardi Jewish music or "Klezmer" music and inject it with a "tonic" mixture of Jewish, Indian, Celtic and Latin music.

Their repertoire consists mainly of original compositions inspired by everything from Russian Gypsy folk songs to Peruvian Shamanistic prayer. The duo, consisting of Violin/Clarinet and Classical Guitar/Mandolin play regularly in London and Brighton both at public and private venues.
