I think I might have liked to do some different stuff with this one musically, but I had a very specific set of requirements.
This is a battle theme for a rock band themed RPG. Each of the 4 party members uses a different instrument (Guitar, Bass, Drums, and synthesizer keyboard) so I had to stick with those 4, and only those 4. Whenever a party member attacks they stop playing their given instrument and their track in the BGM cuts out. So I needed all 4 instruments to be playing constantly with little to no breaks. So the piece was split into 4 tracks designed to be mixed on the fly in game.
