For a live PA I'd much rather there was a combination of well known stuff and new stuff and it was mixed such that it fits in with what you want. I've heard a few PA's that are just carbon copies of released stuff done live which were good and I've heard ones where it's been really jammed up together and messed about with, which are also very good.

Both sides have their positives and their drawbacks, just playing carbon copies of tunes you aren't doing anything you couldn't have done with the vinyls so people don't feel it's as truely 'live' as it could have been, jamming it up freestyle means some people will be pissed off with tunes being changed about or whatever.

I the end though I think a mix between the two works out best, you (hopefully) know what your most popular tunes are so you can use these tracks and just lamp them fairly straight out twisting them up a bit but not too much and use that time during your set as a breather so you can plan out how to turn stuff inside out afterwards.

As for all new tracks and stuff. Nothing wrong with it per se, but people do expect to hear certain tracks from people, well known signiture tracks especially. It doesn't mean it can't work though, I mean last year I saw Subhead and I'm a great fan of their filthy take on wonky techno and I hadn't heard a single track before, but I still loved it to bits.

In the end though I think you are best just telling everyone else to **** off and doing what you want to. No point really going out of your way to appease someone, if they are coming to you then they are interested in what you are doing so the idea of worrying over stuff once you've kcked your PA stuff off the ground is a bit unwarranted.
