So fun story about how I learned about Sigh. I was never huge into black metal (still not) so I never got exposed to them through that. I actually got tickets to see Zimmers Hole when they were on tour with Sigh and Unexpect. Then Zimmers Hole dropped from the tour, and I decided to go anyway (why waste the tickets?). Best decision I've ever made.
It was the most insane show I've ever seen. I'd never heard of Unexpect before that show, but holy shit were they incredible live. Their bass player got so into it that he fell off the stage at one point; didn't miss a note. Their video for Unfed Pendulum actually captures it pretty well (minus the fall):
Then Sigh took the stage. I was not ready for Sigh. Here's how I described it at the time: "The drummer and guitarist look like fairly run of the mill guys, someone you'd pass on the street and not look at twice. Their bass player dresses like he's in an old school thrash band. The keyboard player/singer/multi-instrumentalist guy was dressed like Dracula. The female vocalist was wearing a leather bikini top, leather miniskirt, at least one studded belt, and platform boots. Then she got the saxophone, and shit got weird."
