For those that knew him or knew of him, his partner posted on Facebook that John Kelman passed away this morning, of a massive heart attack. He was an active music reviewer, mostly on All About Jazz I believe.
Rest in Peace, John.
Yeah, I saw him here in Phoenix on Tuesday as well. It was a fantastic show IMO.
One review I read said the 2nd mic was a condenser microphone, another described it as a vintage mic "slathered in distortion". It definitely gave his voice a different sound, which I thought suited those tracks well.
Here's a great live in studio recording that shows the use of each microphone.
