A piece I wrote, after an event, at the long-defunct Blue Gallery (the actual performance took place outside the space),which I attended on 23 September, 1989 (along with my friend, artist Roman Scott). Nirvana (as a replacement for a band called Cat Butt!) had performed at The Blue Gallery, just a few months prior to the flag burning -- I wish I'd seen that concert.
Roman also made a short film (almost certainly lost, in all formats) of the episode, using a PXL-2000.
