Book Of Ryan is nearly upon us, and fans are getting ready for Royce Da 5'9"s most important album to date. While we can expect plenty of autobiographical detail from the legendary Detroit emcee, it's safe to assume that we'll get some bars served up on deck. We've already heard talk of "Caterpillar," which features none other than Bad Meets Evil collaborator Eminem. Paired with yesterday's tantalizing "B.M.E." Instagram post, it's no wonder than talks of a reunion are in the air. 

Evidently, we won't have to wait much longer to hear Em and Royce's latest collaboration. Royce took to Instagram to reveal that "Caterpillar," along with a potential music video, will be dropping tomorrow at approximately 3PM Eastern Time. It's been a while since we've heard BME - but some new music from the duo is always welcome. 

The track is produced by Symbolic One aka S1, and features Eminem going in for well over a minute. Rest assured, if you're looking for Em on his hip-hop tip, you won't be disappointed. For the record, several people have mistakenly concluded that Logic will be featured on the track. Unfortunately, Bobby will be saved for the remix, but rest assured that his verse will proceed to silence even his most ardent critics.
