en CB01 OFFICIAL. Thinking Twice features the pianist Katharina Wolpe playing music composed by her father Stefan Wolpe. Stefan Wolpe’s work is renowned for its originality and rigour, its sense of space and surprise. The unique and vital contribution of this important avant-garde composer continues to influence many young composers of today. The title is taken from a series of lectures given by Stefan Wolpe. In its lucid editing of piano keys in motion, and especially in close up shots of the pianist's hands and face, Jayne Parker "attempts to reflect the rigour of the music" (in her own words).
