What's prog? I've auditioned folk before. I went about it by recording some rough tracks of an original tune and told him to come in for a bit with the rest of the band and be prepared to play that particular tune. Makes everything a bit more relaxed when he/she knows exatly what's going to go down and gives him/her a chance to prepare. In this case it's going to be different because there is no set band. I'm just going to have to tell them upfront that they're not up to par (I hope I don't have to because it's so hard to get musicians together in this **** city, northern ontario). It's almost like they're part of the band without even hearing them so it'll be hard to say, sorry pal, you suck. c'est la vie.
