Thanks Tony. Yes, in a more controlled situation, I would mix the harmonies down a bit, but as stated - that was a fast demo with no editing. Not sure when I'll be similarly inspired, and have the time, but hopefully soon.

Naturally, it's not accurate, because my acoustic vocals are very present in the small room, so the recorded value isa little less than perfect, but it serves a purpose for learning and critique.
