Over the course of his career, Warren G has released five LPs. 1997's Look Over Your Shoulder and 1999's I Want It All were among his most successful, going on to reach gold-selling status, and generated hits such as "I Want It All" and "I Shot The Sheriff," a cover of Bob Marley's popular song by the same name.
