Crys were offered a deal to record a single if they agreed to put Welsh lyrics to their existing songs (which had previously been performed in English). The band complied and the resulting single "Cadw Symud / Lan yn y Gogledd" was released in 1980 on Click Records. The single featured Verden Allen (Mott the Hoople) on keyboards and was recorded at Pete King's studio in Swansea. The line-up by this time was completed by Alun Morgan (Lead guitar) and Nicky Samuel (Drums). The name 'Crys' is a Welsh word that translates into 'Shirt' in English!
The band's profile continued to rise through appearances on Welsh radio and television shows, which ultimately led to a recording contract with Sain Records. Their debut album Rhyfelwr was released in 1981 and their second Tymor yr Heliwr was released in 1982. Both albums gained airplay on Radio Cymru and BBC Radio Wales and they also became the first Welsh language band invited to perform a session on the BBC Radio One Friday Rock Show hosted by the late Tommy Vance. They performed a total of four songs, two in Welsh and two in English, for the session. Both albums won the 'Best album of the Year' award at the annual 'Sgrech' awards show - a Welsh language music industry event. The band continued to perform live throughout Wales and even made a promotional video for the "Merched Gwyllt a Gwin" track from their second album.
The group disbanded for an extended period of time before recording a third album Roc Cafe in 1995. Original lead guitarist Alun Morgan had emigrated to Canada by this time and was replaced by Mark Thomas. The album was released on Compact Disc by Fflach Records and included a free sticker.
The band have made numerous live and television appearances over the last few years, including a brief reunion of the original line up when Alun Morgan visited Wales.
