A new winter challenge
Hi guys, i'm going to have a charitable gig on 11th January. The thing is it is going to be my first concert outside, on fresh air, in the center of my city. Yeah, and I believe the temperature will be around 0 celcius degrees (i think it's 32 fahrenheits). There will be, I presume circa 2000 people. So, do you have any suggestions and advices how to prepare for this gig and warm up voice for singing out in the cold?
