Brian Wilson, an eclectic genius whose sunny Beach Boys songs like "God Only Knows" and "Good Vibrations" helped define American pop music, has died.

Wilson has passed away at the age of 82 following a battle with dementia, his children revealed in a June 11 social media post.

The death of the poet laureate of adolescent heartbreak was announced by his family on Wednesday: “We are at a loss for words right now.”
