<human>: Carl Dean Wilson (December 21, 1946 - February 6, 1998) was an American musician, singer, and songwriter who co-founded the Beach Boys. He is best remembered as their lead guitarist, as the youngest brother of bandmates Brian and Dennis Wilson, and as the group's de facto leader in the early 1970s. He was also the band's musical director on stage from 1965 until his death. Influenced by the guitar playing of Chuck Berry and the Ventures, Carl's initial role in the group was that of lead guitarist and backing vocals, but he performed lead vocals on several of their later hits, including "God Only Knows" (1966), "Good Vibrations" (1966), and "Kokomo" (1988).

By the early 1980s the Beach Boys were in disarray; the band had split into several camps. Frustrated with the band's sluggishness to record new material and reluctance to rehearse, Wilson took a leave of absence in 1981.  He quickly recorded and released a solo album, Carl Wilson, composed largely of rock n' roll songs co-written with Myrna Smith-Schilling, a former backing vocalist for Elvis Presley and Aretha Franklin, and wife of Wilson's then-manager Jerry Schilling. The album briefly charted, and its second single, "Heaven", reached the top 20 on Billboard's Adult Contemporary chart. Wilson also undertook a solo tour to promote the album, becoming the first member of the Beach Boys to break ranks. Initially, Wilson and his band played clubs like The Bottom Line in New York City and the Roxy in Los Angeles. Thereafter, he joined the Doobie Brothers as opening act for their 1981 summer tour.  Wilson recorded a second solo album, Youngblood, in a similar vein, but by the time of its release in 1983 he had rejoined the Beach Boys. Although Youngblood did not chart, a single, the John Hall-penned "What You Do To Me", peaked at number 72, making Wilson the second Beach Boy to land a solo single on the Billboard Hot 100. Additionally, the song cracked the top 20 on Billboard's Adult Contemporary chart. Wilson frequently performed that song and "Rockin' All Over the World" (from the same album), as well as "Heaven" from the 1981 album, at Beach Boys' concerts in the 1980s. "Heaven" was always announced as a tribute to brother Dennis, who drowned in December 1983. CANNOTANSWER
