Can I record your concert on a video and/or audio device?

As long as you’re not selling it, that’s OK with me. Lots of bootlegs are already floating around YouTube and the like (if you have a particularly good audio or video version of a show, let me know because I may want a copy myself). But you should check with the venue first – sometimes they have rules about this sort of thing, and even if the artists says it’s OK, they still say no. Also please don’t do anything that’s going to mess with other people’s enjoyment of the show: a 24-foot jib camera would be a problem, likewise an array of microphones suspended by wires from the ceiling. And finally, be aware that when there are cover songs, I can’t give you permission to do anything with them, so you’re on your own.
