According to several sources, Lupe Fiasco is fronting a rock band called Japanese Cartoon. The side project, which Lupe has yet to officially confirm, reportedly features the rapper as "Percival Fats," singing with an affected British accent on the three tracks that have leaked, which can be heard via the band's MySpace page.

The band also lists seminal punk bands Joy Division and The Clash as influences, along with The Killers and Radiohead, and has recorded a cover of the title track to The Prodigy's upcoming album 'Invaders Must Die,' which features vocals that sound very much like Lupe's.

A blog post on the band's MySpace profile, however, claims that "Percival Fats (Born Percival Hindenburg-Fats) Is not Lupe Fiasco (Born Wasalu Muhammad Jaco). Although, he is a dear friend." The post continues, "Lupe does finance the band but is not, I repeat, not the singer in Japanese Cartoon. He is however the producer and we value his participation very much."

Lupe has a new DVD coming out in March, and claims that his upcoming album will be his last as a solo rapper.
