I like jazz, especially the more adventurous forms, including free jazz and the abstract and fusion periods of Miles Davis and John Coltrane beginning in the mid 1960's until 1975.

The Bimhuis is a great jazz club in Amsterdam, with concerts almost every day, and I used to go there regularly when I lived in Amsterdam.

If you are new to jazz and need some recommendations, these are some all time classics:

• Miles Davis: Kind of Blue (the most classic jazz album; someone to whom I recommended this likes it a lot!)
• Lee Morgan: The Sidewinder (classic hard bop recording from the legendary Blue Note label)
• John Coltrane: A Love Supreme (very spiritual music)
• Keith Jarrett: The Köln Concert (Keith Jarrett's legendary piano solo concert that became a huge seller)

I created a rather complete discography of legendary jazz instrumentalist, composer, writer and painter Marion Brown (thanks to Horst H. Möller for his invaluable contributions).

I am a jazz moderator at Discogs.

I used to produce some music using electric guitars, basses, drum machines, synthesizers and other electronic stuff, record them on a cheap 4-track analog tape recorder and master them on digital audio tape (DAT). In 1998 four tracks made it on a 12" E.P. that was released by my good friends Marcus Hacker and Reinhard Wimmer on their (now defunct) label Transmitter Schallplattenproduktion under the name Karl-Michael Schneider E.P. (SW-TR 003).
