Go immediately to get Billy Harper's 'Capra Black' (but then of course, I would recommend that, given my avatar) and to the Clifford Jordan 'Glass Bead Games'. Also, the mandatory Tolliver's are the two LIve at Slug's volumes, the Live at Loosdrecht, and the two Music Inc. big band volumes (1971 and 19757). But there are a lot of wonderful albums on that link.
