I don't keep up with breh so I don't know if he's told these stories before but this was a dope interview, he said he did "I'm Leaving" off the Firm album all in one take and Dre wasn't tripping and he was supposed to be the only feature but AZ thought they were putting on for Queens so he decided to sneak Half-a-Mill in there as well.
As for the hook on "Superthug", he said he would go in the booth and repeat "what what" as a way to count bars then come back later to lay the hook but Pharrell thought it sounded dope the way it was and told him to keep it.
