Derelict Hands with Calum Borthwick (Scotland) and Russ Callison (US) play Sechs Kleine Klavierstücke by Arnold Schoenberg (1874–1951), arranged by Calum Borthwick. Schoenberg was one of the most influential musical minds of the 20th century regardless of what labels people slap onto his music. Op. 19 is originally a set of pieces for solo piano. You don’t hear Schoenberg on guitar very often. FYI, they recently put out their debut album, Eyes to the Future.
