she “records” her live performances. she said it could go horribly wrong if she started out the wrong way.
here’s how she does it: she goes on stage with her guitar and a tambourine. she has this foot-work recording stuff that plays recorded things in a loop. she records herself banging on her guitar which creates a beat for the whole song. she then strums a rhythm which will also play in a loop with her guitar-banging. she records a few tambourine beats that plays in a loop too. now, she has a beat to play to. she then records herself clapping and singing “woo-hoo”. not only she just recorded her back up beat to play to, but she also recorded her own back-up vocals!
and during her performances, she would kick her tambourine to create more back up beats, and even plays the “trumpet” with her slightly closed fist.
