Don't know why this hasn't gotten any feedback yet. I'll do it.
The intro is pretty boring. I think the drum samples need to be tuned up a bit. Neat synthwork. Is that Slayer? Ah, hear comes a gated synth. Nicely done. Too quiet, though. Gets repetitive. Neat chearing sample useage.
Overall, I think you got some neat ideas going on. Never heard the original, so I couldn't judge it as a remix, but it's good work in itself. I think you just need to add a bit more to the percussion to vary it up, and make the main bit less repetitive by adding another synth or two, or changing the melody after a while. |
