A part of the musical collective Soulquarians, producer J Dilla served as a frequent collaborator of theirs.[1][2] Although album tracks such as "Left & Right" and "Devil's Pie" help to bring this claim to light, Dilla himself was not officially credited for production. However, he contributed significantly to Voodoo's overall sound, specifically the rhythm and percussion.[1] Q-Tip was originally intended to contribute a verse to the song "Left & Right", but was replaced by rappers Method Man & Redman during recording due to creative differences.[3] Questlove has stated that "general opinion was that the song was cool but nobody was feeling Tip's verse".[3] According to former A&R representative Gary Harris, D'Angelo's manager Dominique Trenier "thought that Tip’s verse was wack".[4]
