Astral Progressions has been described by the Wall Street Journal as "stellar jazz-funk… heavy on virtuosic jazz solos…".

The Good Men Project explores the LP's cultural significance: "The album explores West CoastG-funk and two major historical components of Afrofuturistic sound art: spiritual cosmic jazz in the vein of artists like Pharoah Sanders and Alice Coltrane, and cosmic funk as created by Parliament-Funkadelic".
