The original 1957 performance — kotos and marimbas alongside HP varieties like the Chromelodeon and the Harmonic Canon — with splendid artwork including rare documents and photographs.

Thirty-four verses of expanded duets, the prototype of Delusion Of The Fury, thrashed out with the Gate 5 Ensemble over a three year period starting late in 1962, in a too-small space within an abandoned chick hatchery in Petaluma, California.
Plus a section of a rehearsal session, with HP himself giving direction, ending with a fine performance by Danlee Mitchell and Michael Ranta.
And finally a previously unreleased recording of Partch playing Adapted Viola, in one of the Verse 17 duets excised from the final opus.

This is a great way into Partch, revisiting with gusto three well-known, relatively-compact works — a highly rhythmic dance piece, a cross-cutting film score, and Barstow, with HP intoning hitchhiker graffiti.
