If you like your acid house served up hot, bubbling and squelchy like grandma used to make it, then look no further than this German duo, best known for the track Acperience 1, which was something of an anthem in the 1990s.
They are recognized virtuosos of the TB303 synthesizer, which is the signature instrument of acid house. Their music has an easy confidence to it. It tends to start with a beguilingly simple riff that begins to twitch under your skin, nothing too flashy - they have time. Then they slowly layer it, make it denser and deeper, taking you with it, until you find yourself reaching a climax where you feel it cannot go any further, and then it glides you over a plateau for a while and you find yourself at a new point, still moving in a slightly changed landscape. Great music for running. Really really good for running. I have run my best times listening to Hardfloor.
