The sixth PEK Solo effort of 2020 in Boston-based improviser and composer David Peck's series, this album is a followup to his Clarinet Family album earlier in the year, here creating a virtual symphony of saxophones by layering his composition in the studio through four separate recordings, working in the vein of Rova Sax Quartet or the World Sax Quartet.

Using a vast array of instruments categorized by clarinets, double reeds, flutes, free reed aerophones, strings, electronics, electroacoustic sound-makers, percussion, duck calls, sirens and voice, David Peck layers his improvisation into four renditions of himself, which he refers to as a Quartet of PEKs, this work focusing on new instruments developed by Tim Kaiser.
