Zeal and Ardor is a Black Metal project by Manuel Gagneux, a Swiss-American musician who had previously created a project called Birdmask, that he describes as Crycore. Zeal and Ardor’s debut album ‘Devil is Fine’ was first released on Bandcamp in 2016 and re-released by MVKA on February 24, 2017. Gagneux wrote and recorded the album himself (source).

The album’s core idea is based on one question: what would it sound like if slaves had sung songs that didn’t praise god, but satan. The result is a highly unique mix of Gospel, Jazz, Pop and Black Metal. Gagneux apparently got the idea in conversations on 4chan (source).
