Michael (Mikey J) Asante AKA MKJ It’s not often that you come across a British producer with the ability to produce chart hits, DJ, write songs, co-run a dance school and throw a successful pyjama party for his 25th Birthday. But Mikey J, (the J standing for jester), is all of these things and more. And although he’s yet to be a name on the lips of the many, he’s fast establishing himself as a secret weapon for any record company looking to combine underground vibes with crossover appeal. It was his engineering work on street anthems like Sadie Ama’s .
