If you were asked in 1972 which of the Wilson brothers (Carl, Dennis, or Brian) would still be around to reach age 80, surely the famously once reclusive Brian would never have topped the list. But here we are celebrating Brian Wilson’s 80th birthday today (born 6/20/42). The Beach Boys co-founder has had a long and winding road to 80, yet has created one of rock’s most influential song and harmonic books. Watch Wilson perform his masterpiece Pet Sounds live in London in 2003.
