Carl Dean Wilson (December 21, 1946 – February 6, 1998) was an American musician, singer, songwriter and record producer, known as one of the founding members of the Beach Boys. The younger brother of bandmates Brian and Dennis Wilson, he was originally the band's lead guitarist, but he later sang lead vocals on some of the band's most famous songs, like "God Only Knows" (1966), "Good Vibrations" (1966), and "Kokomo" (1988). After Brian's reduced involvement with the group due to mental health issues in the 1970s, Carl became the de facto leader of the Beach Boys, and produced most of their subsequent material, with production nominally credited to "the Beach Boys". He died, aged 51, of lung cancer in 1998. Carl released two solo albums during his lifetime, Carl Wilson (1981), and Youngblood (1983). A posthumous album, Like a Brother, was released in 2000, featuring material recorded with Gerry Beckley and Robert Lamm in the 1990s.
