Here is a short compilation of tracks and links, which could give you some basic ideas about the state of this genre at the moment.
The list starts with the talented Australian DJ and producer tyDi, whose presented track is created with the help of the great female DJ Rap and continues with familiar European Dance Music titans like Gareth Emery (working with Armada and considered to be predominantly a trance producer), Hardwell (also working with Armada music),
Avicii (who's mainly considered as pure house music producer) and the famous German duo Spencer and Hill (generally considered to create pure house music). There aren't more important facts so have a nice listen :)
