Montrose was an American hard rock band formed in 1973 and eponymously named after guitarist and founder Ronnie Montrose. The band's original lineup featured lead vocalist and frontman Sammy Hagar, who later found greater success as a solo artist and as a member of Van Halen. Rounding out the original foursome were bassist Bill Church and drummer Denny Carmassi. The band experienced moderate success before disbanding in early 1977. History Prior to forming the band Montrose, guitarist Ronnie Montrose had been a successful session musician, playing (along with future Montrose bassist Bill Church) on Van Morrison's Tupelo Honey album produced by Ted Templeman, and on albums by Beaver & Krause and Herbie Hancock. He was also a member of the Edgar Winter Group, playing on the hit single "Frankenstein" from the best-selling album They Only Come Out at Night (1972). The original Montrose lineup, consisting of Ronnie Montrose on guitar, Sammy Hagar (then known as Sam Hagar) on lead vocals, Bill Church on bass, and Denny Carmassi on drums, was formed in early 1973 after Ronnie Montrose decided to leave the Edgar Winter Group. Both Hagar and Carmassi had previously worked together and were recruited from local San Francisco-area cover bands, while Bill Church and Ronnie Montrose were acquainted from their session work with singer Van Morrison and producer Ted Templeman. This prior connection provided the band with access to Templeman who heard their demos and helped the newly formed group secure a deal with Warner Bros. The band, as yet officially unnamed and billed as 'Ronnie Montrose and Friends', made their public debut on April 21, 1973 via a 45-minute radio broadcast aired on KSAN FM's Tom Donahue show. The broadcast featured the band's complete ten song performance recorded at the Record Plant in Sausalito, consisting of their entire first album (excluding "Space Station No. 5") as well as the unreleased tracks "Roll Me Nice", "You're Out of Time", and "Roll Over Beethoven". The broadcast was in circulation as a bootleg recording for years before being released in 2017 on the Deluxe Version of their first album. Their debut album, Ted Templeman-produced Montrose, was released on Warner Bros in late 1973. Though the album was not a big seller upon its initial release, peaking at No. 133 on the U.S. Billboard chart, it proved to be an international sleeper hit which over a period of several decades has sold
