Question for Sophie

Sophie,

I have just started doing some work in a local jazz club and wanted some advice from you on available light photography during live performances. The club is small and using a tripod is difficult. I was using a 18-35/f3.5 zoom and a 50/f2, all manual focus. Any tips or techniques that you find useful, I would love to hear. Here is an example of some form the last show I did.
