"This is easily my biggest undertaking to date, in terms of project size, complexity, and length... Since 1994 I wanted to be part of the soundtracks of my favorite games (something which has not changed to this day). What HAS changed is my ability to do so, and create something that fans of the original tracks could appreciate -- and I could be sure I've created a solid tribute instead of a pile of garbage. It took many years for me to be confident enough in my abilities to satisfy all of the above, and I think the time has arrived. The tune herein lightly references the Briefing and Descent Title Themes (in the intro and outtro respectively) but is otherwise a heavy rearrangement of Callisto Tower Colony (Level 12). Level 21 has an extremely similar feel to Level 12, but it is certainly its own track, and I consistently referenced Level 12 while building this arrangement. I do not diverge much rhythmically in the supporting parts (aside from the actual rhythm section) and did not change melodic elements a great deal, but the arrangement and instrumentation should speak for itself."
