I am currently putting Unconscious Collective's "Pleistocene Moon" on Tofu Carnage Records into Sunday morning rotation. Same Genre, more or less: Godspeed You! Black Emperor's catalog, and The World Is A Beautiful Place And I Am No Longer Afraid To Die catalog. The Dear Hunter also has some nice recordings, more Prog-ish.
I like to "Play It Loud" stuff Mahavishnu "Birds of Fire". Also Billy Cobham's "Spectrum" and "Obscured By Clouds" (Tommy Bolin AND Billy Cobham fan boy ;). And Zappa's "Hot Rats"
I have a copy of George Antheil's "Ballet Mechanique" a 1955 Mono on Columbia Masterworks that I bought in Mint condition, which is what I play on the dedicated mono system. I also enjoy his "Symphony No. 4 1942/ Estancia" on Everest (in mono), but not an outstanding player...just good
I like big band, Benny Goodman's "Carnegie Hall" is a keeper, several versions to choose from (Sing! Sing! Sing! well, sings). I like the Cowboy Bebop records from The Seatbelts, and The Seatbelts in general. I also like The Toshiko Akiyoshi- Lew Tabackin Big Band, and their solo projects. I prefer the Japan issues.
I picked up the recent "Evening at the Village Gate" by Coltrane and Dolphy. The original recording on tape was a tough source to start with, but I like it as an artifact of a time and place, which asks that one put his or her Golden Ears aside for a brief time and enjoy your Manhattan, smoke your Lucky Strike and watch the light play on her pearls; knowing this is a Once In A Lifetime night.'
More often, for me it is the music and the performance, and not so much the technology involved in reproduction. I spend much more on media than I do equipment. I'm just an emotional guy, not so analytical.
