Finding Poly-Rythmo singles with covers is pretty rare, and this is one of those releases that hardly ever come up. Discogs only records one ever sold for $200 and this is in better condition than that one (and I didn't pay anything like that for it). However, I don't do it for the money or rarity but the music. And the twp songs are immense (as is nearly always the way with Poly-Rythmo - and given I've got 160+ releases from them this is pretty extraordinary)
Yeah, Elvin has got quite a few good albums on Blue Note , Putting It Together is a good trio date , he released some good stuff on Enja in the 80'/90's as well , I've got a few on CD (In Europe, Youngblood, It Don't Mean A Thing ) Illumination ! with Jimmy Garrison on Blue Note is good too !
