Celebrating 40 years as a performing ensemble, the West Coast saxophone quartet ROVA of Bruce Ackley on soprano saxophone, Steve Adams on alto & sopranino saxophones, Jon Raskin on baritone saxophone, and Larry Ochs on tenor saxophone, reworked compositions from all members transversing their past 34 years, in an absolutely impressive and diverse album.

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.

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.
