I’m not doubting the vocal quality as recorded, but watch the guitar player. He is playing from the start but the guitar sound kicks in at about 55 seconds.
Well, however they did it, I’m not sure. I admit listening to it on my laptop speaker only makes me wish more I had a good 44KHz, 16 or 24 bit stereo recording that I could play on my Polks...
The only way is SDA...
