A seasoned D.I.Y. extreme metal unit based out of Bern, Switzerland, Breakdown of Sanity employ a punishing blend of breakdown-heavy metalcore, post-grunge, and nu-metal. Founded in 2007 by guitarist/songwriter Oliver Stingel and vocalist Carlo Knöpfel, the band soon added bass player César Gonin, drummer Thomas Rindlisbacher, and second guitarist Sandro Keusen to the mix, the latter of whom was replaced in 2009 by Christoph Gygax. The band issued their debut LP, The Last Sunset, independently in 2009, followed by [MIRRORS] (2011), Perception (2013), and Coexistence (2016). Since 2020 they released 3 singles: Traces (2020), Black Smoke (2021) and Collapse (2023).
