The Heavy Sound Community Reach & Impact bus - an out-of-service single decker, sourced by the social enterprise company and is being turned into a mobile community centre offering support, advice and music-making activities to disadvantaged communities.
Jordan Butler, founder of Heavy Sound says: "If we can use rap, hip hop, or song-writing to engage with troubled young people we can help turn their lives around too."
In the first collaboration of its kind, Heavy Sound is working with Police Scotland's Violence Reduction Unit (VRU) and the Scottish Prison Service (SPS).
Since January, volunteer prisoners at Saughton jail have stripped out the bus interior, and transformed it, installing hi-tech recording equipment.
