Lubomyr Melnyk (Germany, 1948) devised "continuous music"  for his piano compositions that is closely related to minimalist repetition: a continuous flow of rapid arpeggios that generates overtones melting into each other.
This translates in a very fast playing technique, up to a dozen note per second.
