I also create my backing tracks in BIAB, and then move them as WAV files onto an SD card in my JamMan looper. The looper then gets plugged directly in to my Bose L1.

I have about 80 songs on the looper. Each song has a number, which I can scroll through using the looper's foot pedal. As a guitar player, I like having this "hands free" feature at gigs. As a back-up, I have all the songs on a small MP3 player, just in case.
