This John Zorn CD I bought years ago and had mixed feelings about it and a few other Zorn CDs I purchased. It goes without saying that if you are having mixed feelings (or second thoughts) about an artist, you will stop spending your hard earned money on him/her.

Fast forward to when I happily started using Spotify and could listen to an album before buying it and I can now explore Zorn freely and pick and choose songs I like. I just put together this John Zorn Book Of Angels playlist I titled John Zorn 1 BOA (book of angels). It comprises the first 8 BOA sessions in chapter "1". When time permits I plan to make 3 more chapters covering all of the BOA sessions to give a listen.

I listened to BOA Vol. 1 in its entirety and it is by no means "chaotic noise" Some of the songs were quite enjoyable.
However if you like to use genres for music/artists I would not call Book of Angels Volume 1 "Astaroth" jazz.
I do not know what genre I would call it. Maybe abstract music? world music?
