James, most shows require a photopass for the Troubadour if you're using a DSLR. I would recommend contacting the performer to ask for that, otherwise you'll have to bring your camera back to your car. Oh another thing, don't be surprised about the DSLR restrictions, otherwise there would be a flux of other vloggers doing the same thing in somewhat mass numbers.
I don't think it's a restriction, but definitely call and ask. Would hate to say no and when you get there it is one.
