When Tupac was signed to Death Row, he was also writing music for other rappers. Including Suge Knight's good buddy MC Hammer.
Pac was known to have done a lot of work on Hammer's unreleased album Too Tight. The album's title track, which Pac wrote, has finally leaked in CDQ.
As you can hear, Hammer is mimicking Pac's flow in the track. The pair recorded 'Too Tight' in 1995. By the next year Hammer's career had been permanently damaged by bankruptcy, and Pac had been gunned down way before his time.
