The band's musical style is a mixture of heavy and melodic classic rock, inspired by Iron Maiden, Kiss, Ozzy Osbourne, Van Halen, Mötley Crüe, Deep Purple and Led Zeppelin.

In 2007, keyboardist Larsen and bassist Visnes left the band, with the latter wanting to focus on Gorgoroth and Sahg, and the former needing more time for his job as a primary school teacher and playing with Enslaved.

Later that year, Audrey Horne released their second studio album, Le Fol, produced by guitarist Isdal, and co-produced and mixed by former keyboardist Larsen, who also contributed keyboard parts.

Le Fol received good reviews in both Norwegian and international press and earned Audrey Horne a Spellemann Award nomination in the Metal category.

[11] The tour took the band through Denmark, Germany, Belgium, United Kingdom, Netherlands, France, Spain, Italy, Austria, Slovenia, Switzerland, Czech Republic, Poland, Lithuania, Latvia, Estonia, Finland and Sweden, before ending in Norway.

The album was mixed by Barresi at his studio and featured then-touring bassist Espen Lien and keyboard contributions by touring member Eyolf Nysæther and Herbrand Larsen, the latter also serving as a recording engineer.

[13][14][15] The years following the release of Pure Heavy was spent touring and playing festivals in Norway and Europe, while the members of the band also focused on other commitments and musical projects.
