Peter Oundjian, the Toronto Symphony music director whose career as a violinist was cut short in 1995 by focal dystonia, is to pick up his instrument again. In April 2012 he will partner his former teacher Itzhak Perlman in a one-off performance of Bach's Concerto for Two Violins. Oundjian was first violinist of the Tokyo Quartet for 14 years until illness forced him to make the  switch from bow to baton.
