FM are a London melodic hard rock band whose polished AOR sound made them one of Britain's enduring names in radio-friendly heavy rock. Formed in 1984 by members including Steve Overland and Merv Goldsworthy, the band arrived with Indiscreet, a debut that captured the era's love of big choruses, clean guitar muscle, keyboard sheen, and soulful vocals. Tough It Out, Takin' It to the Streets, Aphrodisiac, and later comeback albums such as Metropolis, Rockville, Heroes and Villains, Atomic Generation, Synchronized, Thirteen, Old Habits Die Hard, and Brotherhood show a group committed to melodic craft across multiple decades. FM fit hard-rock scope through guitar-driven arrangements, arena-rock lineage, and ties to the British melodic rock scene, even though their style is smoother than metal. The band's strength has always been songwriting discipline: verses set up clear emotional stakes, choruses land with lift, and Overland's voice gives the material warmth rather than empty gloss. FM's music is built for listeners who value hooks, musicianship, and professional polish, but at its best it still carries the heart of a working hard rock band.
