Thunder Seven is a concept album by the Canadian Heavy Metal band Triumph, released in November 1984. It was the band's seventh studio album. The album examines the actions and abnormalities of man at the turn of the 21st century. The album was certified gold in the US by the RIAA, with sales of over 500,000 copies, on April 21, 2003, almost nineteen years after its initial release. "Follow Your Heart" was the band's highest charting single of the time, reaching #88 in both the UK and the US. Though another single was released under the form of "Spellbound", the single didn't prove as successful, only charting in Canada, and barely scraping the top 100. Thunder Seven was the last Triumph album to not feature any outside writers; prior to this, no album featured non-band songwriters since Rock and Roll Machine (1977). Artwork The album cover was illustrated by artist Dean Motter and was a mechanized version of the Vitruvian Man by Leonardo Da Vinci. The cover is a visible element of the album's concept, in which the band examines the actions and abnormalities of man at the turn of the 21st century.
