A Collective Subconscious (ACS) is an instrumental post-rock duo from Portland, Oregon that formed in the winter of 2012. Over the next year the band worked extensively on material for live shows and what would become their debut album, titled "Entheogens."

Having been compared to musical acts such as Mogwai, Godspeed You Black Emperor!, Jakob, Tool, and Isis, A Collective Subconscious bring their own unique style of vast, atmospheric, heavy, and melodic instrumental post-rock. On stage, ACS delivers an intriguing array of sound and live video that's complimented with themes of social commentary, nature, industrialism, and the abstract.

When asked where the band gets its' influences from, members Cory (guitar) & Brian (drums) comment, "It's quite simple...Everyday, consciously or unconsciously we're gathering information about the world in which we live. Our instincts, desires, likes, dislikes, and intelligence are channeled from the subconscious and then released through song."
