Hanna Pakarinen. The Eurovision fame resulted in the release of two singles, 10.000 Ways and Forevermore/Face in the Mirror, which both went straight to the top 3 in the Finnish single charts. Finally, the efforts of the previous studio sessions came to fruition when Thunderstone’s fourth studio album Evolution 4.0 was released in March 2007. 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. Again, a Finnish tour and summer festivals followed.

Around this time, Mirka Rantanen founded the side project band Hevisaurus, which has seen heavy media coverage as a children's music band that plays heavy metal.
