Spectral, since 2012 the working horn trio of Dave Rempis on alto & baritone sax, Darren Johnston on trumpet, and Larry Ochs on sopranino & tenor sax, split their time between San Francisco and Chicago, in their 3rd album of spontaneous, complex free improv, here using the setting of Bunker A-168 in Mare Island Shoreline Heritage Preserve, CA, to influence their performance.

The West Coast Rova Saxophone quartet in a 7 track studio album from 1995, from Jon Raskin on alto saxophone, baritone saxophone, sopranino saxophone, Steve Adams on alto saxophone, sopranino saxophone, Bruce Ackley on soprano saxophone, tenor saxophone and Larry Ochs on tenor saxophone, sopranino saxophone.

Led by bassist Lisle Ellis with a fierce San Francisco contingent, this 1993 studio session brings together saxophonists Christopher Cauley, Joe McPhee, Glenn Spearman, and Larry Ochs with guitarist James Ruthier and drummer Donald Robinson, delivering energetic free jazz rooted in the 1960s tradition but propelled by raw interplay, bold horn lines, and committed group momentum.

Inspired by Larry Ochs' Rova and Darren Johnston's collaborations with Rempis, this free-improvising trio began life in 2011, developing an "invisible architecture" that guides their playing, as heard in these seven superb recordings.
