i think there needs to be more to it before it can be classified. i feel like riffs cant really be classified because they can be changed so much before its a song. maybe youll throw in some weird time sigs and itll be proggy, or maybe youll raise the tempo and drop the tuning and itll be metal. see what it turns into.
