Seventh Wave was an English psychedelic and progressive rock duo formed in the mid-1970s.
The band was formed by Ken Elliot (keyboards, vocals) and Kieran O'Connor (percussion), both of whom had been members of earlier progressive rock groups, Second Hand and Chillum.
Produced by future Motörhead producer Neil Richmond, and signed to the UK based label, Gull, distributed by Motown in the US, together with other UK bands of the day such as If and Judas Priest, Seventh Wave released their first album, Things to Come, in 1974.
Joined by other musicians, including Pete Lemer, Hugh Banton (organist of Van der Graaf Generator), Steve Cook, Brian Gould, Tony Elliott, Pepi Lemer, and Rob Elliott, for their second album, Psi-Fi (1975), the band enjoyed a brief success but broke up after the USA tour promoting the album. Kieran O'Connor continued to perform in blues-rock bands, but died in the 1980s. Ken Elliot went on to write the theme tunes to ITV's lunchtime news bulletin First Report and BBC2's Out of Court.
