Rock It Out! blog‘s “How to be a hardcore singer” video features Andrew and Athon of Black Tusk explaining how they maintain their fine singing voices night after night. You can struggle through the way over caffienated host’s shtick or jump to about 4:24 in the video to get right to Savannah’s finest. I don’t want to ruin it for you, but apparently they have never had vocal lessons and warming up for a gig (or being interviewed) involves drinking beer. Black Tusk rules.
