Patrick Stump banned other musicians from his solo album.
The former Fall Out Boy rocker admits he struggles to "relate" to other musicians, so felt it best that he sang and played all the instruments on his debut LP, which is due for release later this year.
He told MTV News: "I play everything on the record. And I'm kind of being very strict about that, because it's one of those things where I've always wanted to do it, but also because I've had a lot of friends I've wanted to work with, and it's sort of a nice blanket rule to work under, because then I don't have a sea of guests on the album.
"Plus, I feel like some musicians are really good at relating to other musicians and improvising on the spot. I don't know if that's my strength. I'm more of an internal musician ... I groove a lot better with myself than I do with other people, so it's a different sound altogether."
The 'Sugar We're Going Down' hitmaker also joked that playing everything himself gave him the opportunity to finally drum on a record as Fall Out Boy's drummer Andy Hurley was too good for him to get the chance when recording with the group.
He added: "And it's also this big, convoluted way to get me to play drums again, because I really just miss playing drums. And there's no reason for me to play over Andy, because he's a really good drummer."
