His brief time in the big leagues with Columbia Records now over, tenor saxophonist David S. Ware returns to his indie roots, but minus the blowtorch attack that made him the most explosive jazz screamer in the improvising underground. Corridors & Parallels is a very different-sounding Ware record and a different-sounding free jazz record. There's a levity and open-ended interplay here that the tight quartet has never managed before, largely because of Matthew Shipp's decision to switch from piano to synthesizer. On both the proper tracks and the unnamed interludes, Shipp plinks out Sun Ra-ish bursts of electronic noise, eerie whooshes and piercing electric piano riffs. Ware's response is to temper his tenor squalls slightly. The soft touch works, and when he really lets go it's devastating.
