The albums consist solely of electric guitar instrumentals and improvised solos (mostly) played live by Zappa and featuring a wide variety of backing musicians.

The three title tracks are all derived from the song "Inca Roads"; various other solos were taken from "Conehead", "Easy Meat", "The Illinois Enema Bandit", "City of Tiny Lites", "Black Napkins", "The Torture Never Stops", "Chunga's Revenge", and "A Pound for a Brown on the Bus".

The final track, "Canard du Jour", is a duet with Frank Zappa on electric bouzouki and Jean-Luc Ponty on baritone violin dating from a 1972 studio session.
