Sketches of Pain

I am recommending Sketches of Pain, an album by the Dutch electronic artist Sam Samshuijzen. While it is not strictly microtonal it is microtonal in sound design and combined at moments with 12 tet.

The only caveat => the music is encoded in the open source OGG format.
XMPLAY or FireFox will play the music files.

Stream the whole album (Total time = 28:12 ) in Firefox here:

It is work based largely on an EMS analog synthesizer used to design and perform sounds in the style of musique concrete with more abstract music.
