These are sides recorded during a brief summer lull in the life of Trane's famed quartet, the majority of them issued previously on the albums INFINITY and FEELIN' GOOD. The album has the spacious intensity of Trane's latter-day compositions that jar, probe, and bend the horizontal and vertical dimensions of his earlier music while finding stability in the seasoned vigor of the band. "Living Space" appears without strings here, its melody overdubbed by Trane, in unison, on both tenor and soprano. It has the searching, mysterious quality of a mantra unlocking unseen doors, and recalls the waxing fire of A LOVE SUPREME'S "Resolution." "Untitled 90320" offers perhaps the most free environment of the five cuts, with McCoy hanging chordal fragments in thin air as Elvin sympathizes energetically with Trane's excursions into unexplored harmonic vistas. Think four dimensions or more.
