At the heart of the Beach Boys, one of America's biggest bands ever, are two men: Brian Wilson and Mike Love. Brian is the songwriter and resident genius, and Mike is the cocksure frontman. For most of the 1960s, their partnership worked as the Beach Boys scored dozens of hits. But a conflict over the magnum opus "Pet Sounds" revealed that Brian was out to pursue high art at all costs, while Mike prefered to stick with "the formula." For the next 50 years, this battle has raged over what truly constitutes the "real" Beach Boys.
