Cool, dry air dries out the vocal cords, as opposed to warm, moist air, which keeps things nice and loose. I'm not a singer, but that's how Roy Khan explained it to me. :Spin:
This show was crazy good! Definitely worth the hour long trek to my best friend's place and then the two-hour drive from there. The Webster Theater, however, can kiss my ass. Seriously, it had to be about 400 degrees in that place - How f'ing STUPID!!
