Thematically, the album is much darker than the band's multi-platinum debut. "2 X 4" is about Hoon's experience at a drug detox, the country-tinged "Skinned" is about serial killer Ed Gein, "Car Seat (God's Presents)" is about Susan Smith who killed her children by driving her car into a lake in Union, SC, and "St. Andrew's Fall" is about suicide by jumping from a 20-story building. When asked about "Mouthful of Cavities" the band's guitarist, Rogers Stevens, was quoted as saying, "It's probably about the convoluted nooks and crannies of Shannon's brain." It featured haunting harmonies between Shannon Hoon and female vocalist Jena Kraus. Alternatively, "New Life" is about the birth of Hoon's daughter Nico Blue, "Wilt" is about having bad breath, although in Captain Beefheart-esque lyrics, "Galaxie" is about Hoon's experience with his car, a 1964 Ford Galaxie, and "Lemonade" is a tongue-in-cheek song about a bar brawl.

It was like, 'What?'"
