South African grindcore three-piece from the Vaal Triangle (south of Johannesburg), formed in 1993.

Their first demos were released in 1994, with things looking promising thanks to a run of split singles, compilation appearances, and overseas performances.
After a troublesome attempted relocation to Europe, the band returned home and split in 2001.

The band reunited briefly to open for Sepultura on their South African tour in 2014. A world tour to mark 25 years of Groinchurn is being considered for 2019.

Christo Bester: Bass, vocals
Mark Chapman: Guitar, vocals
Sergio Christina: Drums

Christo Bester has recently gone on to form an Afrikaans (!) grindcore band by the name of Insek.
