In the mid 1960s, with hits like Surfin USA and Good Vibrations, the Beach Boys became the carefree sound of American youth. On stage the three brothers and cousin that formed the backbone of the band seemed like one happy family but nothing could be further from the truth. Its lead singer songwriter Brian Wilson battled with his mental health and the legacy of an abusive father. His drug-addicted brother Dennis redefined the meaning of excess. And frontman Mike Love’s obsession with the bottom dollar clashed with the rest of the band’s creative ambitions. Mental breakdowns and bitter fist fights would overshadow much of their 20 year reign as one of the world’s greatest ever bands.
