On the subject of music theory (which I am a novice in, but love to geek out about), would recommend Adam Nelly and Trevor Wong on youtube. Neely has some exploratory/experimental stuff for different styles, and Wong focuses on emo/math rock. Not sure how relevant that’ll be for GBA hacking (although an emo FE soundtrack sounds neat to me). These two are a bit more advanced and niche, but fun (For me at least) to learn about.
I actually would advise against watching Neely’s videos; they’re very unstructured and don’t really go into proper analysis, which is not a good foundation for beginner music theory. They’re fine if you want something interesting but you won’t gain much practical music theory from them. He’s more interested in shocking/engaging viewers than he is in teaching them.
Yeah, I wouldn’t recommend them to a beginner, but interesting to watch if you get more advanced. Agree that his stuff is less instructional by nature.
Genuine suggestion: consider remaking the soundtrack you did for THWD. Even though Agro’s scathing review on them was fairly accurate, you’ve since clearly learned and grown as a musician and I feel you might like to consider remaking the THWD tracks with the things you have learned. There is honestly some potential in them with some fairly sick beats.
The project is done, if I did go back and redo any of them it’d just be for shits.
However I did make like 19 tracks for Fractured Realm (project link here) over the past few months if you wanted to check those out. Most of them are in the current public build (and for the time being I’m too lazy to share them here).
