Big Sean is back in beast mode.

As he gears up for the release of his fifth album this fall, the Detroit-bred rapper is revealing more details about the highly-anticipated project including some of his collaborators.

Post Malone appears on “Wolves,” a track about family, which also features ad-libs from A$AP Rocky. “[That song is about] my family growing up,” Sean tells Entertainment Weekly. “Everybody’s in there, my grandma, my mom, my brother — it’s like they were a pack of wolves and they were the sweetest and strongest. It’s one of my favorites on the album.”

Rocky also guests on another song with MadeinTYO. “Rocky had a verse on [‘Wolves’ originally], but he ended up doing the verse to another song that he and I felt fit a little better with the album,” he adds. “That’s another song I got with MadeinTYO. But I just kept it dialed-in throughout.”

In addition to “Single Again” and the A$AP Ferg-assisted “Bezerk,” Meek Mill and Diddy make cameos. “There’s a song where Meek Mill just says two lines, and Puff had a couple of lines,” reveals Sean.

For the first time, he also opens up about being diagnosed with a heart disease at the age of 19. “I couldn’t even walk from one side of the room to the other without getting super-tired,” he tells EW. “I passed out once in the shower and got rushed to the emergency room.”

He addresses the scary moment on “Lucky Me,” crediting his mother’s holistic medicine for curing him. “Lucky me, I was diagnosed with a heart disease at 19,” he raps. “Doctors said they had to cut it open put a pacemaker on it to put it back on beat / ‘Til my mother took me to holistic doctors and they prescribed me magnesium for two weeks / Went back to the regular doctors and they said, ‘Huh? damn, looks like we don’t need to proceed.'”

Sean does even more personal reflection throughout the album, his first solo project since 2017’s I Decided. “I took some time to work on myself and I was able to have a good therapist, good mentors,” he says. “I truthfully feel like it’ll really shine through on the full album.”
