Montrose was formed in 1973 in California by guitarist Ronnie Montrose. Known for their powerful, guitar-driven sound, Montrose released four studio albums during their original run: Montrose (1973), Paper Money (1974), Warner Bros. Presents Montrose! (1975), and Jump on It (1976). Their self-titled debut is often regarded as one of the greatest hard rock albums of the 1970s. Despite numerous lineup changes, the band was known for its influential and iconic sound, fronted initially by vocalist Sammy Hagar. The original era ended after the Jump on It period, but Ronnie Montrose revived the band name in 1987 for the album Mean with a completely different lineup and later returned to touring as Montrose with vocalist Keith St. John and a rotating cast of musicians. Over the years, the band underwent multiple lineup changes with a revolving door of talented musicians who contributed to its legacy. Montrose’s impact on the rock genre remains significant, marked by classic tracks like “Rock Candy” and “Bad Motor Scooter.”
Ronnie Montrose
Ronnie Montrose was the founding guitarist and namesake of the band, forming Montrose in 1973 after previously working with artists including Van Morrison and Edgar Winter. He was the driving force behind the band’s distinctive sound, characterized by powerful riffs and a raw, energetic guitar style. Ronnie played on all five Montrose studio albums: Montrose (1973), Paper Money (1974), Warner Bros. Presents Montrose! (1975), Jump on It (1976), and Mean (1987). His influence extended well beyond Montrose as he formed Gamma in the late 1970s and released numerous solo albums. His career also included work with Herbie Hancock, Boz Scaggs, Van Morrison, and the Edgar Winter Group. Ronnie Montrose died on March 3, 2012, at age 64.
Sammy Hagar
Sammy Hagar was the original vocalist for Montrose, joining in 1973 and contributing to the band’s first two albums, Montrose and Paper Money. Hagar’s powerful and dynamic vocal style helped define the band’s sound during its formative years, with standout performances on tracks like “Bad Motor Scooter” and “Space Station No. 5.” Hagar left Montrose after the Paper Money tour in 1975 and went on to a highly successful solo career before joining Van Halen in 1985. He later formed Chickenfoot and Sammy Hagar & The Circle and has remained one of rock’s most enduring frontmen.
