[2] Thunderstone was formed in early 2000 by ex-speed/thrash guitarist Nino Laurenne[3] as a side project; his first demo was recorded at Sonic Pump Studios.
By the summer of 2001, Kari Tornack joined the band as a keyboardist, and Thunderstone evolved into a quintet.
Recorded at Sonic Pump Studios in Helsinki (with Laurenne as guitarist, producer, and engineer) and mixed by Mikko Karmila (Children Of Bodom, Amorphis) at Finnvox Studios (Sentenced, Moonspell, Stratovarius), Thunderstone ended the year with a strong presence on numerous year-end "Top Metal Albums Of 2002" lists.
In 2003, after being named "Newcomer of the Year," by the readers of Rock Hard Magazine, Thunderstone celebrated their accomplishments with an extensive European tour supporting Stratovarius and Symphony X. Thunderstone returned to Sonic Pump to record their second album, The Burning.
Showing a darker side of the band and moving them away from the “power metal” of their first release, the album was liked by the fans and entered the Finnish charts at No.10.
Late in 2007 the band posted this statement on their official website: "We are sad to announce that Pasi Rantanen and Kari Tornack are no longer part of Thunderstone.
In late July/early August 2013, Thunderstone's official Facebook page made several announcements, including that both singer Rick Altzi and drummer Mirka Rantanen would be parting ways with the band.
In early February 2014, band announced on their official Facebook page, that their new drummer is Atte Palokangas (Agonizer, Before the Dawn).
