The world knew him as Cat Stevens, an artist whose songs conquered the hearts of a generation. But after selling over 40 million records, he turned his back on the music industry, mystifying his fans. Since then, Cat Stevens' search for his own identity has taken him on an extraordinary journey, and has led him to a religion often times misunderstood: Islam. In a world of fear, his effort to create a greater understanding of his faith has often times met controversy. After nearly two decades away, he is back fighting to spread his message of peace through music.
