High Tide was an English rock band, formed in 1969 by Tony Hill (guitar and vocals), Simon House (violin and keyboards), Peter Pavli (bass guitar) and Roger Hadden (drums).
High Tide made their first recordings as the backing band on Denny Gerrard's album Sinister Morning. Gerrard returned the favor by producing their first album, Sea Shanties, which was released in October 1969. Though it met with a scathing review in Melody Maker, reviews in the underground press were universally positive, and sales were just enough to convince Liberty to give the green light to a second album.
This second album, High Tide, was released the following year. A third album was being recorded in 1970, but Roger Hadden, who had been suffering from chronic mental instability and depression since before joining High Tide, had a mental breakdown and was hospitalized before the album could be finished. Unable to continue without Hadden, the group split up.
