Today, my highschool bigband went touring two more elementary schools. We do this to advertise our music program to children graduating from elementary going into HS. There is no Jr. High in Quebec. So when we arrive at the second school, there is no power, probably because it is raining. We set up everything anyways, just incase the power would come back on before we start, but it didn't. So we came up with a solution. We used the truck which we use to carry all the instruments and equipment to power the amps and PA using a converter. It worked. But, a few times during the show, the bass amp shut itself off, and I had to turn it back on in the middle of songs.Also, I couldn't raise the volume too high on it either. Anyways, the kids liked us, and it was successful. Has anyone ever played during a power outage/failure? What solutions did you come up with?
