Hardfloor is a German techno duo, consisting of Oliver Bondzio and Ramon Zenker. Their most famous track is "Acperience 1" (titled simply "Acperience" on many compilations).

Their distinctive acid house sound is credited to their virtuoso skill at manipulating Roland TB-303 bass synthesisers, they reputedly use up to six of these machines at once, some of which are highly modified. The group were criticised for their formulaic but commercially successful remixes, but their own releases consistently explore new territory.
