I’ve always had trouble producing reasonable-quality recordings of piano playing, but I managed to dig up an old microphone that works okay. While I’ve been doodling around with improvisations for years now, I only recently came across the improvisations of Keith Jarrett, which are highly original and inspirational. His Cologne Concert performance is probably the most famous, but I’m partial to his Paris Concert, perhaps because of its classical strains.
Here’s a clip of one of my own unpremeditated improvisations. I still find myself resorting to little crutches here and there, but if I deliberately try to push the envelope, the results are usually surprisingly–occasionally they are jarring, but you learn to roll with it! The rhythmic staccato portion around 2:45, for instance, definitely represents a departure from my comfort zone, but in a positive way.
