there is definitly.. or at least with techno/techhouse.

to me i think its just a need to explore into music further yet at the same time keeping on board what you know. house & techhouse are some what more musical in a traditional sense so will there for, most likely be explored by the more musical producers (alanis definitly being musically gifted). i cant see some nose bleed schranz bootlegger going down the house route but even some of the harder acid bods have done it very succesfully - chris liberator & davethedrummer's HA-LO project on eukatech for example.
