Carnal Diafragma is a Czech goregrind band formed in 1997 in Ostrava. The band's songs do not include any lyrics. Known for their instrumental songs, the band has experienced several lineup changes throughout its history. They have released four studio albums as well as a number of demos and split albums with other groups.
Carnal Diafragma was formed in Ostrava in 1997 by Robert "Roà ¾an" Roà ¾anski (guitar, vocals), Milan Jaà Âák (vocals), and Michal "Kameà Â" Kaminski (drums). The band played noise and grindcore, occasionally touching on pornogrind themes, before settling on their current genre of goregrind. They were joined by LukÃ¡à ¡ "Stezi" Stejskal on bass, though he left in 2000 and was replaced by David "Sabon" SnÃÂhota. In 2001, Stezi returned and the band recorded their first album, Preparation of Patients for the Examination. In 2003, Carnal Diafragma released a split EP with German band Ulcerrhoea. A year later, they released the demo cassette Daddy's Steak. Following this, Stezi definitively left the band. In 2006, Carnal Diafragma recorded their second full-length album, Space Symphony Around Us. Kameà  left the band at this point and was replaced by Ondà Âej "Prune" Podeà ¡va. In 2009, Sabon and Prune left and the band took on Libor "Porky" Philipp on drums and Martin "Sabon" SnÃÂhota (David's brother) on bass. In 2011, Carnal Diafragma recorded their third album, Planet of Children's Heads, and the two SnÃÂhota brothers switched places once more. In 2015, Milan Jaà Âák left the band and singer Martin "Kino" Vaà ¡ek was hired in his place. That year, Grind Monsters, a split EP with Mexican band Fecalizer, was issued. A year later, the band's fourth studio album, titled Grind Restaurant pana Septika, came out. In June 2017, Porky left the band and was replaced by current drummer LukÃ¡à ¡ JelÃÂnek.
