Fair Warning: This isn't an album review. It's a light pop-cultural study of one of Rock's most interesting dramas: Van Halen's career. The departure of David Lee Roth due to creative differences with the Van Halen brothers after the mammoth success of 1984 shattered the hopes of many a teenaged hair-band wannabe. After all, this band was ascending beyond the more good-but-cookie-cutter hair metal bands that were emerging at the time and were superstars. What followed was, if you'll pardon the pun, the Best of Both Worlds.
