"I'm not great at mixing and mastering" he said, moments before blowing the audience away

Man, that was AWESOME! Reminiscent of Miranda Lambert's HOUSE THAT BUILT ME, in terms of the underlying message. You benefit from the strong emotional bond felt by everyone who has ever invested years of their life in a place, with all the attached memories... then moved away. Part of the song writing process involves finding ways to get the listener to identify with your song, but in this case you just sort of inherit a ton of that from your topic. Well played, my friend... well played.

I've used BIAB long enough to know that its rare to press a button and generate what you hear in your head. The tasty presentation of each instrument suggests to me that you put some time into this, and it shows.

Nice! I look forward to hearing more from you.
