Q: what was the end of the world concert?
A: during that time, there had been a massive advertising campaign all over the city, saying it was the end of the world on a certain date, (and that we should listsen to their radio station because of it). the claim was completely unrealistic, but it still put me in an emotionally reflective mood the night before.  normally when i record live audio like that i improvise and do crazy stuff, but for some reason i was feeling different that day, and that riff was deeply stuck in my mind for some reason.
