I know a lot of us use BIAB for backing tracks at gigs. In the past I've recorded CD's and played them through my PA.

I going to start using a JamMan "solo" looper pedal. It fits nicely on my guitar pedal board. It holds lots of music (I can use WAV files) onto its SD card. I can simply transfer my files over from my computer and convert them to "single" phrases on the looper. And its all hands free operation at the gig.
