Jim Hall Live! Vol. 2-4 (ArtistShare, three CDs). Previously unreleased recordings made in 1975 by Jim Hall, Don Thompson, and Terry Clarke at the same Toronto gig that produced Jim Hall Live! The latter is by common consent Hall’s best album–a judgment in which I concur–and this set is of identical quality, a priceless cache of wholly involving performances by the greatest living jazz guitarist (TT).
