Whoa! Is Frozencity bitonal? I hear C major for the pizz bass strings but then E major (and a bit of C# minor which is just the relative minor of E major) in the other parts until everything goes into E major later on. This tune makes me want to listen to a tune i made in high school that I made in C major and C# major at the same time that sits in the deep depths of my hard drive lol.
418 also is great vibe! Feels like something from Fez. I swear you are going for bitonality in both these pieces, because I hear you playing a Dmaj7 of the A major riff you keep from the beginning.
Great work!
