Kanye West is back in the studio with Bump J. West offered a peek at their collaboration in an Instagram video posted today (Sept. 14) that also features Ronny J.

The clip shows 'Ye in Chicago picking up Bump in a white Ferrari and heading to a recording studio, where West taps out drums and Bump is seen writing. The footage is set to an unreleased track featuring Kanye singing about "all the homies lost" in a falsetto that recalls his 2000s chipmunk soul.

Bump J, who completed a seven-year prison stint last April, said in a June interview with Fake Shore Drive that West plans to produce a seven-song EP with him and fellow Goon Squad member Sly Polaroid. He previously worked with Kanye during the Wyoming sessions that produced this summer's G.O.O.D. Music releases.

Yeezy contributed to Bump's debut album on Atlantic, Nothing To Lose, but the project was shelved after the rapper was arrested for the armed robbery charges that would ultimately land him in prison. 'Ye also contributed beats on the rapper's 2006 mixtape Chicagorilla.

Bump has stayed busy since being released, including a memorable appearance on G Herbo’s album Humble Beast last September. He dropped his own first post-prison album I Don't Feel Rehabilitated in June.

West was also spotted recently in the studio with controversial figure 6ix9ine. Ronny J, seen manning a laptop in West's new Instagram post, released his OMGRonny mixtape in February.
