"Brain Drain" is the 11th studio album by the American punk rock band, the Ramones. Released on March 23, 1989, it was the last Ramones album to feature bassist Dee Dee Ramone, the first to feature Marky Ramone since his initial firing from the band after 1983's "Subterranean Jungle", and the band's last album released through Sire Records.
The album's development marked a period of increased tension and conflict among band members. Bassist Dee Dee Ramone was especially noted for his escalating addiction to drugs, causing much friction with his bandmates. Having already released ten albums, the Ramones were feeling creatively drained, hence the title "Brain Drain".
"Brain Drain" is largely known for the hit single, "Pet Sematary"—named after Stephen King’s novel. King, a Ramones fan, reportedly requested the track. It later became one of the band's biggest radio hits and was used in the 1989 film adaptation of King’s book.
Musically, "Brain Drain" saw the Ramones staying true to their punk roots while also integrating elements of the heavier speed, and metal genres. The album drew mixed-to-positive reviews from critics, who often saw it as an uneven yet entertaining work, with lyrical themes ranging from humor, anti-politics to heartbreak.
After the release of the album, Dee Dee Ramone left the band. He was replaced by Christopher Joseph Ward, known better by his stage name C. J. Ramone.
