Able to score films, record pop rock or train the next Arthur Rubenstein in a single bound, the Fine Arts Division's Music Lab is a powerhouse of musical creativity.   Each of the seventeen workstations is complete with a Yamaha weighted keyboard/controller, protools/m-box/mac package, finale, digital performer and access to a system wide raid server.   Led by Fine Arts Chair Cathy Thomas-Grant and Professor Lincoln Hanks, Pepperdine's students have all the tools of the professional music industry at their command as they become the next generation of musicians and composers.
