Black Sabbath Dehumanizer Demos May 2026

Recorded at Monnow Valley Studio in Wales, the Dehumanizer sessions were marked by intense rehearsals and improvisation. The band, consisting of Tony Iommi (guitar), Geezer Butler (bass), Tony Martin (vocals), and Cozy Powell (drums), aimed to recapture the raw energy of their early days. These sessions yielded some of the most aggressive and experimental material in Black Sabbath's discography.
