Regrettably the Eastern Rebellion discography on jazzdiscography.com is not up to date, and Tom Lord does not list them as a group entry, e.g. the Vol. 5 is listed with Coleman as the leader. One would have to browse through all of Cedar Walton's dates to find them all. Lord lists only a very small number of sessions besides the later releases on MusicMasters.
That said, I saw them perform with Bob Berg and later Ralph Moore, and it was always superb.
