Wörmdigger was founded by brothers Sandro and Jerome Häni together with Rico Vaterlaus. Sandro and Jerome discovered heavy music in childhood through their father and have written together since 2011, building their sound around dense riffing, raw energy, and detailed studio production. The brothers met Rico during their school years, when he was playing in a punk band while they pursued their own metal project; the three supported one another's music long before formally joining forces. In 2017, Sandro and Jerome opened their own recording studio and began working with artists across Switzerland. When Rico's band split in 2018, he joined the brothers, bringing melodic ideas from his punk background that merged with their heavier influences — sessions that became the foundation of Wörmdigger. Drummer Nicolas Borner joined in 2021 after meeting the brothers through studio work, completing the group musically and personally. The band's name traces back to a joke: Rico used to call the brothers "Würmligrübbler," Swiss German for "worm diggers," a nickname that eventually became Wörmdigger. Second guitarist Felix Straub, previously known to Sandro and Jerome through an earlier studio production, later joined to help realize songs that had originally been written for two guitars, rounding out the band's current lineup and sound. |
