I recently purchased the synth Massive as part of the Native Instruments Komplete 6 collection, and it has some fantastic hard and dirty sounds. So, I decided to put some of them to the test in a sort of electro-house track. I know it's pretty dense for the genre but there are just tons of neat production things in here that I'm proud of.
I picked Team Fortress 2 to remix because almost no one does it, and when they do, they just chop up voice samples in the game, which is a pretty lame way of "remixing" and doesn't take much skill. The themes arranged are "Playing With Danger" / "Team Fortress" as well as the Meet the Spy video music (briefly), "Right Behind You."
