If you go to the Neumond Recordings website, you can actually experience a fictional record company and see an advertisement on youtube. The soundcloud embedded music currently does not work, but they can be found here. The websites appear to be set in the Wolfenstein New Order universe. Really cool Alternate Reality Game. You have to understand German just to figure out the song lyrics or you can probably just look up an english translation of the alternate timeline lyrics online. A soldier singer named Hans is mentioned. Not sure if it is Hans Grosse though.
Edit
It could be Hans Grosse. The voice resembles the one from Wolfenstein 2009. The soldier on the cover has a metal hand, suggesting that Hans had a metallic hand when he recorded the song or he was brought back as a robot clone.
