Leftöver Crack is an American punk rock band formed in 1998, following the breakup of Choking Victim. The band is currently signed to Tankcrimes for CD releases, and Alternative Tentacles for vinyl releases. Leftöver Crack spans several different music genres including hardcore punk, ska, and crust punk. They write mostly political lyrics of a radical leftist nature, opposing religion, capitalism, and authority. Members of Leftöver Crack reside in the C-Squat on 155 Avenue C in the Lower East Side of Manhattan. Natives of New York City, band members have a well-documented history of back-and-forth conflict with the NYPD which precedes the band's formation. The name "Leftöver Crack" is explained by Stza as being "an oxymoron", based on the idea that crack cocaine addicts are known for vigorous use and are unlikely to have any "leftover" crack.

The World/Inferno Friendship Society was an American band from Brooklyn, New York. Its style merged punk, soul, klezmer and jazz, while its collective membership featured horns, piano and guitar and had a membership of about 40 players, of whom only about seven to ten active members usually performed at a time. The group was led by singer Jack Terricloth, who was the only constant during the group's history. Terricloth was known for his pointed commentary during shows; his monologues touched on politics and his transformation from the "old school."
