Nice! Tho' I'd respectfully disagree with the rankings.
For me, Bitches Brew is the seminal Miles work. Had it on CD for the last two decades but recently bagged it on japanese-quad LP from Discogs. Had a nice chat with the seller from over there, the japanese love their fusion! I'd personally also rank Sketches of Spain, Aura, In A Silent Way and Siesta above Kind of Blue.
Bitches Brew Quad is an interesting fresh listen on my pair of studio monitors, tho' it's ideally made for a true 4.0 setup, but rigging up 70's style quad-Hifi to get the true mix-intention is a bit of a mission...not sure if I'll ever get round to it, also got Floyd's Atom Heart Mother on quad LP, so maybe I should...tho' realistically will try a home-made 4.0 faux-quad setup.
On that note...here's the emotional rollercoaster that is Sanctuary from BB:
I'm a purist and really not a fan of anything Miles did post 1963 . In fact I can only just about stomach ESP. I blame the influence of a 17 year old Tony Williams lol . That's not quite correct as one of my favourite Miles Recordings is the Complete Concert 1964 , released somewhat confusingly in 1965.
So yes I adore Sketches and also Milestones but for me Kind of Blue will always be the greatest pieces of music ever written and played.
Quad albums , yes I had a couple in the 70's . The pressings and sound quality was off the scale. Used to play it on a beautiful Micro Seiki DD 40 turntable with SME arm and Ortofon Moving Coil , Harmon Kardon Citation 14 series pre and power amp with Radford Tristar T 90 speakers. Boy I wish I still had that set up!
