Hardfloor is a German techno and acid trance duo, consisting of Oliver Bondzio and Ramon Zenker from Cologne. Their most famous track is "Acperience 1" (often titled more simply as "Acperience" on many compilation albums).
Their distinctive acid house sound is attributed to their skill at manipulating Roland TB-303 bass synthesisers, using up to six of these machines at once. Their UK chart hits include "Hardtrance Acperience" (1992), "Trancescript" (1993) and the remix of the aforementioned "Acperience" (1997). Their 1996 album, Home Run, peaked at #68 in the UK Albums Chart.
