Since then, he has launched a hugely successful solo career, which led to his most prominent role as the lead singer of the group Van Halen. This role eventually led him to be inducted into the Rock and Roll Hall of Fame. In 2008, Hagar formed a group called Chickenfoot, which began its tour after their album rose to #4 on the Billboard Top 100. Hagar’s Chickenfoot concerts have a high-energy party atmosphere, where audience members sing and dance along with songs from Hagar’s considerable repertoire. During his concert, Hagar mixes in old classics with new releases, giving audience members no shortage of nostalgia before launching into new jams, followed by a few more classics and so on. Many of his new songs are featured on "Chickenfoot," the premier album for the group, released in June 2009. In November 2012, Chickenfoot released a live album in a limited edition box-set that featured songs from Hagar, as well as other members of the band.

Hagar’s success began in the mid 1970s with his solo career, which spawned some of his most well-known singles, like "Red" and "I Can’t Drive 55." His solo career would lead to him become the replacement lead vocalist in the band Van Halen after David Lee Roth parted ways with with them in 1985. Hagar stayed in this role for the next 10 years and released singles, like "Runaround" and "Poundcake." Hagar is known throughout the past three decades as a Rock and Roll icon, giving ticket buyers a blast from the past, as well as a look into the present during his concerts.
