ADDITION!: new guitar (the old one was outta tune), new drums (the old snare sounded like a "cowbell" as one review said. muahaha not any more ;)), piano placed in the peril theme (listen and tell me what you think of it... good or bad?), added themes towards the end of the demo, and overall re-mastering of most of the instruments.
once again, i submitted this so that other artists on the NG audio portal can assist me in the creation of the ultimate halo remix.
