Vên was a studio project of Glanzmann's, but its success led to the recruitment of a full band. The band then released a full-length album, Spirit, in June 2006. In November 2007, Eluveitie was signed by Nuclear Blast. The group rose to fame following the release of their first major-label album, Slania, in February 2008.
