we do use biab live and have been for 6 to 8 yrs. we arrange the song and put the words in as a reference points. I can play my on lead or fiddle or mandolin. I use a harmonizer which I send a biab from monitor out. as far as a video I did one for a song I posted on FB. We normally use a mixer run into a pair of Bose towers. we have run threw much bigger set up with SP2,s and 18" subs. biab live works well for us
