Het Zweet was not really a band but one man Marien van Oers, from Breda.
"The music consisted of long 10 minute percussion pieces played on self
built instruments (shopping trolleys amplified with pickups, blown
cardboard tubes etc.) with repetitive shouted vocals by Marien. The
music was often placed in the industrial camp and linked with the likes
of Test Dept but infact Het Zweet were more concerned with ‘tribal’
music, physicality and trance effects." (Information from discogs.com)
