has some of the most well-produced and mixed music I have ever heard for an electronic musician - I have been listening to "Pjanoo" for the longest tiem and then recently clicked another link of in in youtube and was shocked by how clear, well layered, and WIDE the version I was listening to was..
you can hear it here:
Shadows is also really good for mastering.. but Pjanoo seems to illustrate it better:
the wideness is till what gets me though - they actually utilize the back end of the spectrum.. so many of his songs I've listened to I 've just been thoroughly impressed with. All electronic artissts on this site, including myself, should strive for this level of production.
I am sure there are others but I can't think of any atm - feel free to post other artists or other songs from this artist or to discuss this further.
