I could never really get in to hard house and it made life difficult for decent hard trance listening as Mark Eg / M-Zone were not so regular at DA back in 2000/1 - however the Monastry was available too... rats... those were some good times.
Anyway... Hard House probably got so big and advertised so much as it was pretty much a soley a UK affair really... if it was same sound but from foreign country it may of lasted much much longer. But then again... who knows. I just think that it got so big it hit commercial in it's own backyard and then died as things do when their saturated with attention.
In my opinion... hard house? has had it's day, has had so much attention that it would be very hard to not find it mainstream... only so much you can do by blagging a bouncy bass-line like it uses. Imagine if ALL hard trance was using a hennes & cold beat? eww... that would be boring.
Blah Blah Blah...
Rats.
