Any fan of both GP bike racing and Miles Davis is extremely welcome as far as I am concerned. I have "Kind of Blue" in at least 5 different formats and/or versions, and all the classic Miles Davis quintet stuff.
Rebirth of the Cool and Kind of Blue are the inflection points for mine.
Kind of Blue... unbelievable. As if Paul Chambers' powerful melodic contours and Bill Evans' haunting vamps and voicings on Miles' modal vision is not enough already; here comes John freakin Coltrane. Love it.
