'Bout Soul does not mean the same thing as soul-jazz, as the opening track "Soul" makes abundantly clear. Written by Grachan Moncur III and poet Barbara Simmons, "Soul" is a tonally free tone-poem that features Simmons' spoken recital. It's about what the concept of soul is, not what soul music is, and that should not come as a surprise to anyone acquainted with Jackie McLean's work. Even as his Blue Note contemporaries were working commercial soul-jazz grooves, McLean pushed the borders of jazz, embracing the avant-garde and free jazz.
Two dozen rare B-sides from Stax Records’ “blue” period, many reissued for the first time. An enormous and impressive undertaking, “The Complete Stax-Volt Singles 1959-68” box set was issued in 1991. While pleased with its content, hardcore collectors were nevertheless disappointed that it was not as “complete” as it claimed to be, as it featured all the A-sides and only selected B-sides. While highly welcome, its release left more than 100 of approximately 225 “blue period” Stax and Volt B-sides un-reissued in any form. Several of those sides have since featured on CD compilations, either as individual tracks here and there or on Kent’s recent “The Other Side Of The Trax”, but that still left many awaiting reissue. Fortunately, the success of “The Other Side Of The Trax” has warranted this second volume. The 24 tracks here span almost the whole of Stax Records’ blue period, as far back as when the label was still called Satellite.
