I know that the Columbia Jazz Masterpieces series sounded OK in later years, but the very earliest CDs in the series (which had Columbia's most popular jazz recordings, like Kind Of Blue by Miles Davis) had a ton of noise reduction piled on, and sounded horrible. Those were released in 1986. Jazz Goes To College (CK 45149) was reissued in 1989 so it's safe from the tampering.The Dave Brubeck Quartet Jazz Goes to College. This CD was part of the Columbia Jazz Masterpieces series. They put the original liner notes into a booklet which includes the dates and locations of the original recordings but they don't give the dates of the remastering or give the year that the CD version was created. Not a big deal - just curious.
