I like Lightening Bolt, own one album by them and would love to see them live.
Apparently they don't play on stage, but on the floor in the middle of the audienceโฆ. in this case surrounded by a barrier.
Apparently, for extra non-conformity they sometimes start their set within a few seconds of the support band finishing.
The line up is one guy on drums/vocals (vocals are into an old fashioned telephone stuck to mask which he wears) and one guy on Bass (G string replaced by a banjo string).
