Dundertåget was a Swedish rock band known for their spirited and gritty approach to music, rooted in classic rock with a distinctly Scandinavian touch. The group's origins date back to when they were formerly known as Thunder Express, named after a song by The Hellacopters, one of the member's previous bands. They made the transition to singing in Swedish and changed their name to Dundertåget, which could be translated as "The Thunder Train," which reflected the powerful and unrelenting energy of their sound.

Among their most notable releases, "Det tog en lång tid" (It Took a Long Time), "Dom feta åren är förbi" (The Fat Years Are Over), and "Bara till besvär" (Just a Nuisance) are tracks that exemplify their robust musical style—a style characterized by vigorous guitars, compelling rhythms, and memorable hooks. These songs capture the quintessence of Dundertåget's approach to music: candid, raw, and unapologetically rock 'n' roll. They managed to make a significant mark within the Swedish music scene before eventually disbanding, leaving behind a legacy celebrated by fans of the genre.
