In the mid-1970s, Hagar started a solo recording and touring career to increasing success. He enjoyed moderate success on Capitol Records under the tutelage of A&R man Carter, with such albums as Nine on a Ten Scale and hits such as “Red”, which would build his persona and style, leading to his nickname of “The Red Rocker”. However, Hagar felt that Carter did not play to his strengths as “a heavy-metal guy” and instead tried to generate Top 40 hits (such as a cover of Otis Redding‘s “Dock of the Bay“) with little success. Hagar was scheduled to open for Boston in San Bernardino, California, during their 1979 world tour. Prior to the Boston show, Hagar was replaced on the bill by the up-and-coming Los Angeles club band, The Knack, rather than being an opening act so close to his former hometown of Fontana.
