Would you care to elaborate on what you meant? I'm guessing you meant the mix wasn't dubstep? Granted, not all of it was strictly dubstep, but the mix was recorded over four years ago. It's basically a snapshot of what the scene was like before people like Skrillex came along and turned dubstep into the formulaic joke that it's now become. The dubstep scene was pretty varied from the early 2000's until it got killed by commercial radio. In a few short years I guess we've now gone through terms such as 'Post-dubstep' 'Bass music' and 'future garage', but back then we could still call it dubstep because the sound it has now become associated with wasn't all there was to it.
