Hip-hop music has been expanding all over the world in recent years. With the growing popularity of hip-hop music, the world's clubs and discos are now filled with DJs. These scratch-masters keep the parties jumping with the hottest beats and sounds. A Los Angeles-based DJ school,Scratch Academy, has taken advantage of this trend. At the school, experienced DJs teach people ages 6 to 60 the art of hip-hop music. Students get hand-no experience as DJs by accompanying their teachers to practical sessions in night clubs. P.D. Wilson has just graduated from the academy and is hoping to have a successful career working in clubs,as well as at private parties.
