Bölzer is a Swiss duo that approaches extreme metal from a unique angle: somewhere between black and death, with room for melody, dynamics, and the occasional (clean) vocal as a counterpoint. Without bass but with a remarkably full guitar sound, they combine repetitive motifs with sudden outbursts; reviewers call this mix simultaneously atmospheric and captivating, from their first EP, Aura , to the album, Hero . On Sunday, March 15th, they'll be performing with extreme metal bands Misthyrming + Vitriol + Trepaneringsritualen at Patronaat!
