Like others. I have Quebec, Quinichette, Quattlebaum, & Quartet Out.
Also came across:
Quartet + 1 - Bob Ackerman, Pam Purvis, Wilber Morris, Denis Charles, Herb Robertson (Cadence Jazz Records)
and
Henry Qualls: Blues from Elmo, Texas (Dallas Blues Society)
Probably the only blues record in existence with a cover of the Newbeats' "Bread and Butter" on it.
