Man, I was looking for a good Tenacious D remix on the Newgrounds, and I finally found it!! I can't express it with words how much I adore this band, and your remake was so damn great! It sounded a bit milder and more soulful to me then the original, unfortunately I don't know anything about music-making so I can't help you with any useful comment on the details, the only thing I can say is that the riffs were really good and heavy, I liked them even better then in the original. It's a great piece dude, Kyle and Jack would be proud of ya ;))
And... If you'll be able to, please make more remakes of Tenacious D (my personal love goes to Beelzeboss, Master Exploder, Tribute, Explosivo, Kielbasa Sausage... Well, anyway I'm sure you know their best pieces yourself). I'll be looking forward to seeing your works.
