What's goin' on?! This is the 4th Hypersonic radio show, first broadcast on Scratch Radio 28/2/17. After the phenomenal success of Stormzy's album release, I spent a lot of time this week listening to all my favourite Hip Hop and Grime and decided to pick a playlist based on that music. You can expect music from Biz Markie, Devlin and Childish Gambino!
