SOMETHING BLUE is five-star stuff IMO. A "pale reflection" of KIND OF BLUE. I suppose... but Horn's relationship with Miles Davis predates the recording of either LP, IIRC. Anyway, SOMETHING BLUE manages to be airier, even more atmospheric than KIND OF BLUE. Not better, mind you. Just different enough. BIlly Higgins has a lot to do with that.
The same band, more or less, made those LPs for Columbia. Nice enough, but they lack something SOMETHING BLUE has.
HIs mid-70s stuff, like ALTURA SO SOL (with Egberto Gismonti) and SPECIAL EDITION, is often fine. Also like what he brings to Cal Tjader's MONTEREY CONCERTS.
Finally, A BUCKET OF BLOOD would not be the classic Roger Corman schlockfest it is without Paul Horn's beatitudes.
