Three proper Miles Davis albums from 1969 to 1975 for £1.38 or £1.48 each; not cheap outtakes of him singing in the shower!
These are from his electric period so if youve only heard Kind of Blue these may shock you.
Pangaea is the most difficult of the three and also the best value as its a 2 CD set.
They are so cheap because of a quirk of MP3 pricing in that they price per track and these albums only contain 2 tracks each.
I can highly recommend all 3 and there are also some other cheap Miles Davis albums with double albums between £4 and £5.
