Alex, I have many "ECM" records, only 1 CD that I can think of; for some reason I never play any of them. So the question is "Why did I buy them in the first place?" There are many things in that same category; bright yellow double knit bell bottomed slacks, with 3 inch cuffs; Why did I buy them, the moths don't even like them.
Things of that nature are just another one of life's riddles. Azimuth - "The Tunnel" is interesting though it's on ECM and is typical of their music.

Enjoy the music.
