The Alarm are an alternative rock band that emerged from North Wales in the late 1970s. They started as a mod band and stayed together for over ten years. As a rock band, they displayed marked influences from Welsh language and culture. By opening for acts such as U2 and Bob Dylan, they became a popular alternative rock band of the 1980s, retaining a small but loyal following to the present day.

Allmusic journalist Steve Huey stated:

The British music press habitually savaged their records as derivative and pretentious, but this meant little to their zealous following, who supported the band to the tune of over 5 million sales worldwide and 16 Top 50 UK singles.

A punk band was formed in Rhyl, Wales in 1977, billed as The Toilets. It contained Peters, Sharp, Macdonald and Twist, and in 1978 their name was changed to Seventeen. Seventeen were a mod band who released a single ("Don't Let Go" / "Bank Holiday Weekend") in March 1980 and toured with the Stray Cats that year. They played their last concert together under the new name of Alarm Alarm, but this would also be the last time this name was used.
