Ysaye's Sonatas for solo violin were sketched out in a fevered twenty-four hours during the summer of 1923, a response to the question of why - in over two hundred years - no one had attempted to follow the path forged by Johann Sebastian Bach. Each of these six new Sonatas is dedicated to and customized around the playing style of a contemporary violinist, and as such they present formidable challenges. Russian virtuoso Alina Ibragimova, whose earlier recording of the Bach Sonatas & Partitas was revelatory, turns out performances fully worthy of this distinguished ancestry.
