Brian Wilson, the legendary leader and singer-songwriter of the American rock band Beach Boys, has died at the age of 82.

On the 11th (local time), according to foreign media such as Reuters and the Associated Press, Wilson's family announced on his official website that he had passed away. The specific cause was not disclosed.

Wilson was the leader, producer, and singer-songwriter of the American band "Beach Boys," which gained sensational popularity in the 1960s. He is known for hit songs such as "Surfin' USA," "Surfer Girl," and "Kokomo."

In 1961, the band Beach Boys, centered around Wilson, along with his younger brothers Carl and Dennis, cousin Mike Love, and friend Al Jardine, achieved success right from their first single, "Surfin.'" Reflecting the culture of young people in California's West Coast, symbolized by surfing and cars, the Beach Boys' music is often credited with pioneering a new genre called "Surf Music."

However, Wilson lived a tumultuous life, plagued by mental illness and substance abuse. He became mentally unstable during a tour in 1966, when the band's popularity peaked, and left the concert.

Although he remained a core member of the band afterward, he continued to work mainly in the studio.

The Beach Boys were inducted into the Rock and Roll Hall of Fame in 1988.

However, Wilson gradually began to suffer from substance and alcohol addiction. His mental health deteriorated to the point where he was diagnosed with schizoaffective disorder, accompanied by auditory hallucinations. He continued sporadic musical activities afterward, but his instability persisted.
