In the market for a children’s book? Probably not. But if you are, The Sonar System is a picture book set on the faraway galaxy of Tesfa, part of a sonar system where instead of a sun, the planets revolve around a gigantic speaker and the inhabitants spend their time building sound systems and listening to music. It’s basically a perfect world. Written and illustrated by Ras Mykha (who’s also a singer and MC for reggae sound systems like Lion Roots), it’s intended as a way of introducing kids to sound system culture. The book forms part of the Sound System Culture national tour, documenting the history of reggae sound systems in cities across the UK. Find a copy here.
