This is pretty weird stuff. Or at least, that’s the way it seems at first. If all you know, as I did to begin with, is that DJ Diamond is a 24-year-old DJ from the West Side of Chicago whose real name is Karlis Griffin, and that Flight Muzik is his debut album, then this will seem like music from another planet – one where notions such as melody, structure and listenability have little meaning; it’s music, but not as most of us know it.
