Crom Cruach was formed in July 2005 by founding members Cathalstrophic (Vocals) and Kradmar (Guitar). Drummer Nocternia joined in 2008.
Their debut album Narcotic Death was self-produced and released in the subsequent year. The sound is raw and much akin to early Black Metal.
In 2010 writing began on their second album Awaken In Darkness - an 8 track album with a more mature, accomplished sound. In August 2011 the album was recorded at Shay's Studio in Loughrea, Co. Galway. As well as being a talented sound engineer, Shay Leon provided an amazing working environment to record in, producing an album of top sound quality without compromising on atmosphere.
In 2013, following Nocternia's departure and Slaine taking over on drums, writing and recording began on 2014's Rebirth. This is a double album with the first half heavy, almost Doom-like. The second half is acoustically driven and experiments with shamanism. Lyrics and vocals are kept on a minimalist , simplistic basis, with the music rhythmic and entrancing.
After a year's hiatus Cathalstrophic returned in 2015 to complete the resurrection of Crom Cruach. Their sound altered again giving it a more aggressive and upfront edge, more akin to the chaos of 70's Punk than to modern Black Metal, placing it between early Venom and The Sex Pistols, with a dash of Mayhem.
The title of their first post-reunion release, Defilers Of The Noise, is a reflection of this new direction. Little time was wasted in getting the album written and recorded, again employing the services of Shay Leon for recording and mastering. The completed work was released in December 2015.
