Reading Ahley Kahn's 'House That Trane Built' book has got me pulling out my Impulse vinyl, starting with these:
Yusef Lateef 'Live At Pep's' (Impulse stereo original)
Quincy Jones 'The Quintessence' (UK Impulse 70s reissue - sounds great. HMV had an A1 set of master tape copies I think.)
JJ Johnson/Kai Winding 'The Great Kai and JJ' (Impulse stereo original, A-1)
Some real gems on this label, not to mention all of those Coltranes...
