The first artist I want to introduce for the Free! Music! Week! 2011 is zero-project.
As versatile as you can get. A wide variety of music. That may describes best what zero-project made since 2007.
Electronic, Gothic Rock, Greek Songs, Soundtracks... it's amazing how many different genres you can find on his site. The songs are under a free license, and zero-project was the most listened artist for over 2 month in February 2011 at Jamendo.
So if you want to take a trip from local tunes into infinite space, you might want to listen to some of the tracks.
