If you go to Fabryka Industrial Rock Free MP3 Downloads you'll see a variety of releases given officially for free by the bands.
The download links redirect to their official websites (where their music is stored) so they have your visits as well and so you can check their news updates at the same time. I find it working fair that way.
We've been selectively choosing the artists to include to fabrykamagazine ;) If you know about any other free releases given by bands officially for a free download and matching Fabryka Magazine approach, let me know please!
