Ras Kwame had heavyweight UK MC and Boy Better Know member Jammer in session on his Radio 1 & 1Xtra show on Sunday. He gave us an exclusive preview of tracks from his new record Jahmanji.

The Wake Up Mix was supplied by DJ B Naughty, a mashup of everything from grime to dubstep to drum & bass, and Ras unveiled another Hottest Homegrown record.
