Original release recorded 02/03/1959 and 22/04/1959.
For most Columbia sessions of the fifties and sixties, the music was taped simultaneously on two different machines. At the first Kind Of Blue session, which produced the three songs on side one of the LP, one of the three-track machines was running slightly slow. As it happens, the master takes used on the LP were pulled from the reels recorded on that machine. As a result, the first three tunes always appeared in sharp pitch until the gold Mastersound edition of this album. Here we have included the music as the musicians played it (newly remixed), and the only complete alternate take from these historic sessions.
