Mark Coles profiles Pulitzer Prize winning rapper Kendrick Lamar, whose concepts and ideas are changing hip-hop culture.

Lamar won the award for his latest album Damn, which also collected five Grammy awards in January and is praised for lyrics which reveal the complexity of modern African-American life.

Growing up in the deprived city of Compton, California, Lamar credits his father with keeping him on the right path and providing the balance that some of his peers were missing. His album good kid, m.A.A.d city tells the stories of young black men trying to escape the negative influences surrounding them.

Lamar's lyrical journey explores violence, depression, religion and also the limits of fame and fortune, he's the rapper who says that helping the next generation find positivity and God is where it's at.
