Royce da 5’9″ is reloaded. Fresh off the release of last month’s PRhyme 2 with DJ Premier, the Detroit rap legend is readying his new album Book of Ryan, which will reunite him with his Bad Meets Evil partner-in-rhyme Eminem.

Slim Shady guests on a song called “Caterpillar.” “The basic theme of the song is, ‘Don’t disrespect the caterpillar to praise the butterfly,'” Royce exclusively tells Rap-Up. “Marshall falls a little bit more into that category than I do, but both of us are caterpillars. A lot of times, you’ll praise these guys but gotta tear us down…But where do you think his style came from?”

As if that bar-fest wasn’t enough, Royce tapped another intricate rhymer for the show-stopping remix. “Logic is on the ‘Caterpillar’ remix,” he reveals. “He’s spitting that brutal honesty and he spit for like 50-something bars. It’s one of those shut-the-internet-down-for-a-couple-of-days verses for sure. I’m proud of him for that one.”

Aside from Eminem, Logic, and J. Cole (“Boblo Boat“), Book of Ryan will also include features from Pusha T, Fabolous, Jadakiss, T-Pain, and Boogie. Most importantly, Royce says the album will consist of his most evolved work to date.

“This is the perfect me to share with people,” he adds. “It’s not the negative me across the board. I still got a little bit of an edge, but I’m grown. I’m thinking right, I’m sharp, and I’m not stuck in a chamber where I’m just making dark music. I’m sober and able to be as introspective as possible. It’s the perfect time for me to open up.”

“Another reason I’m saying this is a better time for me to go this introspective to give you this particular album here, is because I’m a master now of storytelling,” he adds. “I’m very, very good at being able to balance these different things that I’ve been able to learn to do over the years just as an artist and paint a picture for you.”

Book of Ryan is due May 4.
