Prospex is a community-based charity working to improve the lives of young people in the Caledonian Road area of North King's Cross in London. They aim to meet the needs of the young people we come in contact with regardless of race, colour, creed, gender or situation.
Their approach is to first build strong, positive relationships of trust with each young person. They then use those relationships to meet that young person's needs in practical ways and to progress and develop each young person by supporting, motivating, challenging and encouraging them to better themselves.
This government-backed campaign aims to "deliver a music-led multi-media attack on the blatant and subliminal endorsements of gun culture fashion; a hard-hitting, in-your-face, uncompromising reality check for those who have been seduced into this negativity; and a campaign strategy that will carry street cred, artistic integrity and commercial viability."
