Holy shit! Wave Chapelle just dropped off a new 4keys-produced single with Lil Uzi Vert titled “Boss Up!” The Milwaukee duo consisting of Wave and 4keys absolutely slayed this track, and managed to get a heat verse from none other than Lil Uzi! Wave and Uzi have been close friends for awhile now, so it was just a matter of time that he got a verse from him. Nonetheless, this song is a BANGER! Press play below.
