Kaisas has released the fourth lyric video and single from their album IERIA, titled "(She Is Just So) Heavy Metal". This track is a tribute to the women of heavy metal—referred to as "Ierias"—and the accompanying video features 20 female models, paying homage to their role in the scene.

Vocals on this track are performed by Kenny Behnke-Gapp from Germany, with backing vocals by Gordon MacIntosh from Scotland. The two vocalists previously collaborated on Kaisas' earlier album MARTYRIA. The track was mixed and mastered at Tonality Studio in California by Bryan Underwood, with pre-production handled by Canister.
