As he grew older, Smith found a way to escape the effects of his abuse, and his bullying attitude: hip-hop music. He fell in love with it at the age of nine, and by 11 he was writing lyrics and making his own songs with some DJ equipment his grandmother gave him to stop him riding motorcycles or doing karate. Before too long, LL was an established member of the Hip-Hop community in his area. He gained notoriety through his many rap battles against well-established MCs, including the battle against Chicken and Porn that rocketed him to fame.
