For me, the best Howard dates are the two on Freedom, Black Ark and Live at the Village Vanguard. Of course, the stuff with Frank Wright isn't bad either... I'd also like to hear the Live in Torino on Altsax (tho co-released with some obscure Euro imprint). Assume it's got the nice modal/out vibe of his best work.
Wonder where the original Patterns session came from - the band is so weird it's hard to figure. I mean, Mengelberg, Bennink, Boston and Schoonhoven isn't that strange a combo (if it were a Dulfer date, anyway...) but to throw Noah and Earl in there makes it super odd. I think I'm going to put it on right now, as a matter of fact - it's been years since I jammed the thing.
