High Tide was a band formed in 1969 by Tony Hill (guitar, keyboards, and vocals), Simon House (violin and keyboards), Pete Pavli (bass) and Roger Hadden (drums). The trademark of their first album Sea Shanties was the constant battle between the electric guitar of Tony Hill and the electric violin of Simon House. There is hardly a quiet moment on Sea Shanties, the heaviest tracks being "Futilist's Lament" and the instrumental "Death Warmed Up". Stylistically it is a mix of hard rock, psychedelic, blues, folk, and jazz-rock.
The second, self-titled, album is a little less heavy and introduces some keyboards, played by Hill and House; the folk and jazz-rock influences are more noticeable on this album. Featuring just three tracks - Blankman Cries Again, The Joke and Saneonymous - it can be seen as a concept of sorts, the theme being the slow slide into pychosis. Indeed, Roger Hadden was later committed for just that reason.
High Tide also played as backing band on Denny Gerrard's album
