German pianist Florian Wittenburg was created in Berlin in 1973, and studied in holland through the ’90s and (through a scholarship or grant) in Paris in the 2000s. He caused several performers in the areas of music, video, and sculpture through the second option period, including mentioned Russian theremin virtuoso Lydia Kavina and Dutch pianist Nico Huijbregts. Huijbregts made an appearance on Wittenburg’s 2013 recording Sympathetic, (A)Symmetric: SONGS for Piano (with a collection partly influenced by Morton Feldman’s idea of “crippled symmetry”), improvising on three items focused around drones and melodies developed by Wittenburg with piano and E-Bow.
