Over the last few years now, there has been a huge rise in the level of production being outputted from home producers. Nowadays people look for the mixing as much as they do the track itself.
This super-high level of production from even the grassroots has added an entire new edge to genres like tech-house, drum and bass, dubstep and even metal. I believe this is something which could massively boost the hard house scene. Oustanding production is being favoured by many non-dnb listeners for example and people enjoy listening to otherwise very heavy music (Noisia and Skrillex are prime examples of this) if the producer is one sick mofo. When I say outstandng production, I mean originality of song structure and ideas, melody, mood, synth and sample work, use of vocals, use of other instruments, etc.
I think what also needs to be heavy assessed in Hard House are the sets and what tracks DJs are willing to play. Hard House will always be what it is, but there is something about the typical track structure and set progression which is going to soon seem extremely out-dated. The songs are mixed in and out at pretty much set times and the 4/4 element is VERY obvious. The question is, will hard house DJs be willing to play unconventional tunes? I do not know as I'm not active in the scene, but I think that the 145-155bpm range is still up for grabs.
I believe the quality of both production and innovation needs to be pushed further. Something that must be taken advantage of is the 'drop'. Dubstep kids are obsessed with this but the HH equivalent is the bass kicking in during the mix and then when it kicks in after the breakdown. This is something which can definetly be exploited. The fact that Hard House also has room for melody/harmonizing gives the genre an edge too. Hoovers, acid, saw-synths, pads, glitch, rave shots, futuristic type sounds, the genre has many tools which makes it stand out. All this goes down the drain everytime someone bootlegs an old HH tune instead of grafting a new one. You only need turn your head towards the psy-trance scene if you want some examples of insane production.
Push it and make it work. Enough shitty bootlegs and updates, that shit is great but becoming dated fast. I would absolutely love if one day a HH DJ posted something on BT like "Hey guys this is something a little bit different" and posted a mix of some really dubby hard house, or a mix of purely tribalish hard house. Or maybe a production mix of HH with lasers and bleeps and sharp futuristic style sounds.... I'm just coming up with these in my head, but as I said before, I think the 145-155bpm range is still up for grabs right now.
