Spirit World Field Guide is the eighth studio album by American hip hop artist Aesop Rock. It was released on November 13, 2020, through Rhymesayers Entertainment. It acts as a "guide" to the Spirit World. The album was preceded by two singles: "The Gates" released on September 9, and "Pizza Alley" released on October 16, 2020. Both were released with music videos directed by Rob Shaw and featuring animation from Justin "Coro" Kaufman, who also designed the album's cover art. A third single and music video, "Coveralls", was released on November 13 alongside the album.

After over 20 years of collaboration, which also birthed Aesop’s two most popular songs to date (“Daylight” and “None Shall Pass”), Garbology is the first Aesop Rock album fully produced by Blockhead.
