I've been to a few shows where there was a negative reaction to a bands set, but there is one that sticks out rather well..
I am not sure of the year/date, possibly 2002 or 2003? but the Iron Maidens were doing a show at the now-defunct Zephyr club in downtown Salt Lake. We tried to get on the bill through a mutual friend of the maidens, and were told that the local promoter already had the "perfect fit" opening the show, and they didn't know who it was. Oh well...
Fast forward a month to the night of the show. There is a line of rockers and metal heads out the door, and around the block. We were in line lamenting on how it would have been great to get that slot and play in front of "our target audience", when we found out at the door that the opening band was Starmy.
Yes, the name of the band was Starmy. They were well know in the local Salt lake circuit as one of the best indie/post rock/shoe gaze bands. We were familiar with them, and they were okay blokes, However, we were sure the metal crowd would not agree, respect nor enjoy their music. People inside the club were chattering, already making up their minds about not wanting to sit through their set. We knew we were in for a show (or lack there of).
Starmy hits the stage, and not a soul is on the floor. Everyone is back against the walls, sitting at tables and have their backs turned to them while at the bar. This place is PACKED and everyone is actively staying as far from the stage as possible.
A minute into their first song the singer/guitarist makes a comment about how "lame" the crowd was while looking at the floor, strumming his guitar as if he would rather be getting a root canal... and then all hell broke loose.
People started booing and chanting "go home!", as the band kept trudging through their first song. All the other band members of Starmy looked confused and anxious while the lead singer/guitarist just stared at the floor strumming his guitar out of rhythm. I am guessing he was supposed to be singing but was missing his cues.
There was a pause, and the singer/guitarist looks back at the drummer and nods, and they start into another song. Now the crowd is booing and chanting even louder. Then there was a LOUD booming voice from the balcony yelling "YOOOOU SSSUUUUCCCKKK!!!" over and over again. this guy was so loud, you could hear him over the other 250+ angry and annoyed concert goers.
At this point, the singer/guitarist of Starmy stops playing his guitar, takes it off and lightly sets it on the floor causing it to feedback, and walks off the stage. His bandmates are still playing, looking a each other in bewilderment as to what is happening. Then - one at a time - they also stop playing, looked at each other shrugging their shoulders, and then exited the stage themselves.
After 5 minutes, the house lights come on and the whole club erupts into loud cheering and clapping. Starmy starts packing their gear off the stage and the entire club begins cheering and clapping again even louder.
Hey, the promoter said he had the "perfect fit", and Starmy felt they were it too.
So... what did we learn?
