In his very favorable review of the Musical Offering, colleague Dan Davis noted how Savall's unique arrangement of the movements augments the performance's overall impact by forming a structurally sound symmetrical "arch" from beginning to end. Here Savall similarly rethinks the structural possibilities of the work, though his organizational choices function primarily as a means to enrich the impression of the fugues' varied sonorities and contrapuntal textures. Tempos also are generally very reserved, reminiscent of Davis' description of those in the Musical Offering as "startling in their slowness".

PSI is a classic defined German band formed in 1975, consisting of five musicians: Matthias Frey as keyboardist and vocalist, Volkmar Zimmermann as guitarist, Bodo Feldmann as bassist Robert Jahn as drummer, and Wilfried Junkler as saxophonist (also mentioned as percussionist). Frey is a more prominent artist, by solo works and collaborations in the genre, Trilok Gurtu or Wolfgang Tiepold being top personalities with whom he played or made music. PSI's referential style is jazz-rock, typical for the German influence, drawing on the Bavarian School of Missus Beastly, Passport, Muniu, taking however the progressive rock angle through some Kraan-like methods. Keen on an artistically music and satisfied by their improvisation impulse, the band shows class and distinguishes memorably.
