>However putting "hard house" in a search gets all kinds of wrong results!!
There isn't really such a thing as "hard" house any more. Original hard house was the sort of stuff which was played by the late Tony de Vit such as the "Trade" night at The Arches in Glasgow in the 90s. "hard" house then was b*****dised into "hard house" and got faster and harder until it was no longer house that was just hard.
Without knowing specifics of the genres you prefer it is definately hard to help you choose. The main areas are house, trance, techno and electo.
You could search for electro-house which is another kind of b*****disation because electro-house always existed as its own sub genre until all this big swedish house mafia nonsense was classed as electro-house so all the old electro-house producers have swung away from the name so as not to be classed alongside the above and David Guetta and his nonsense.
I am mostly a techno fan and I suggest looking at stuff by:
Richie Hawtin
Sven Vath
BCR Boys (A friend of mine)
Clutch Slip (Other friends of mine)
Umek
Marco Carola
Chris Liebing
Magda
Audion
Dave Clarke
