I agree with Dave, however I am basically an LP only guy. I never liked the Miles CD versions, so when Mosaic pressed these sets, I bought all I could afford.
(Mosaic) Miles Davis "Plugged Nickel" (MO10-158).
(Mosaic) "Miles Davis/Bill Evans complete Columbia Sessions" (MO11-168).
(Mosaic) Miles Davis "Complete Studio 1965-June 1968" (MO10-177).
All of these are EXCELLENT. Dead quiet, music is in chronological order with unedited out takes not available elsewhere. The art work, text and photography are stunning and the liner notes explain artist participation and show recording set ups.
Each Mosaic LP box set is limited edition, each hand signed in the front with ink pen (pressing number + run quantity). A single stamper run from the master tape, typically limited to 3500 copies. On each box the number hand written above the 3500 run number is the place in line your set was pressed (935/3500). Low number stampers continue to rise in price as do all Mosaic sets.
If you can find any of these sets at an affordable price, go for it. I consider mine irreplaceable. They are a work of art.
