If any man in pop history deserved the tag of genius, it was Brian Wilson. As leader, producer and chief composer of the Beach Boys, he displayed an instinctive command of melody, harmony and arranging skills. The result was a run of hits that included many of the most sparkling and creative records of the 1960s. But there was a dark side to this seemingly effortless success, rooted in his tortured family background. No sooner had Brian masterminded such gems as the Pet Sounds album and Good Vibrations than his psychological demons began to derail his life.
