I haven't been keeping up to speed with the Prog Metal world for a long time, and then I logged on to Thresh.net to see how the band was getting on and I see this sad news...
Mac will be greatly missed. He was always great on stage, had a great voice, and seemed to be a genuinely nice bloke.
I wasn't aware of Threshold heading into ProgPower VIII. I got Dead Reckoning to check them out and have been listening to the band non-stop ever since.
RIP Mac. What an incredible voice. Seems like all my favorite vocalists are being silenced (e.g. Midnight).
