Then there's me LOL. I use BIAB/the program right from the laptop. I have been doing this since I started using the program back in 2004 and have played hundreds of gigs without ONE GLITCH. The only other advise I will offer is "force yourself to sing", everyone can, some not as well as others but trust me your audience will listen to the entire package.

I emphasis the singing as an all instrumental gig is hard on both the musician as well as he/her audience.
