My favw Impulse rekkid is my 45 of John Handy's "Hard Work!"
Also...I've never heard an album of his that was good all the way through, but I gotta cop a plea for Mel Brown. That cat was totally underrated. Impulse was not exactly famous for soul-jazz, but Mel did some worthwhile stuff. (I'd also put "Hard Work" in the s-j category, although I understand that most of Handy's records were a little more "out" than that.)
Oh shit, speaking of soul-jazz on Impulse, I forgot - Shirley Scott's Everybody Loves A Lover. You heard of one-trackers? To me, this is a one-sider, but that one side works well. It's the one with "Shirley" (a Chicago steppers' classic) on it
