Elephants on Acid is the ninth studio album by American hip hop group Cypress Hill, and is the group's first studio album in eight years following Rise Up making it the group's longest gap between albums. The album was released on September 28, 2018. The album includes 21 tracks. Unlike Rise Up, group’s last album which was produced by a number of people, this album is fully produced by Muggs, just like the classic first albums Cypress Hill and Black Sunday. The Independent said about the album, "On their first album in eight years, Cypress Hill still sound like no one else." Allmusic reviewer Fred Thomas said that Thirty years into any music career, the pressure is generally off. Cypress Hill, active since 1988 and best known for their weed-friendly gangsta rap hits from the '90s, could easily rewrite and revisit the ideas that made them famous for the rest of their days and fans would delight in the familiarity.
