If he isn’t working with Jay-Z, you might catch record producer Young Guru in the studio or on tour with any number of big-name artists. What we didn’t know, though, is that he is also getting some work in with the notorious DOOM. Here is a track Young Guru apparently produced for the elusive villain, although we aren’t sure exactly where it came from. While the title of the track certainly reads remix, these are raps that we can’t quite identify as being previously released. Also, we are receiving some insider reports that this is indeed a brand new track. Either way, “Doomsayer” kicks ass. We will keep you posted as we learn more, but please feel free to fill us in if you happen to come across any additional information.
