“Keep It Thoro” is the lead single from Prodigy’s debut solo album H.N.I.C. The Alchemist samples the intro of Jack Mayborn’s 1978 track “Disco People.” In an interview with Complex, Al revealed that Prodigy had a cold during the recording of the track, he previewed the track at the Puerto Rican Day parade in New York City, and revealed that a version with a chorus was created with radio airplay in mind:

It was dope because it got heavy radio airplay all day with no chorus. It was a song on the radio, but not a huge radio hit. I remember after the record came out Chris Lighty was like, ‘Yo, the song could be bigger if it had a hook, we need a hook for radio.’

Later, they got Havoc in the studio to put a hook on it and there’s even a version out that ended up going out to radio with Hav’s hook but it just didn’t do anything. The hook was dope too but the song was already powerful enough.
