He is particularly interested in the music of Mieczysław Weinberg, whose complete works featuring a solo violin Roth has recorded.
Roth studied the violin at the Musikhochschule Lübeck with Zakhar Bron from 1983 to 1986, and later with Ana Chumachenco in Zürich and Munich, graduating with a soloist diploma.
Writing about the complex second sonata, a reviewer noted that Roth brought "the necessary level of intensity to bear, marshalling its distinct dialogues, monologues and metrically-different paragraphs".
[5] Conductors with whom he has collaborated include Gerd Albrecht, Herbert Blomstedt, Andrey Boreyko, Dennis Russell Davies, Hartmut Haenchen, Manfred Honeck, James Gaffigan, Mihkel Kütson and Antoni Wit.
[5] Roth's chamber music partners have included pianist Itamar Golan, cellists Nicolas Altstaedt, Gautier Capuçon and Danjulo Ishizaka, violists Kim Kashkashian and Nils Mönkemeyer, oboist Albrecht Mayer, and clarinetist Andreas Ottensamer.
