Strangely enough, I have been to the symphony....waiting for a bus and lady gave me a free 75 dollar ticket, and im like whoa....im so not going to fit in....and low and behold i didnt. twiztid knit hat, black flame t-shirt and lord knows what i was wearing for pants that day, andi i still got respect from the people who were working there, but I was so outta place it was mad funny. hell the old people who were sitting next to me didnt come back after intermission, and no it had nothing to do with my smell, i showered daily then.
it was a over all good experience, but I didnt really get it untill the very end when it all just kinda came together, for me and for the music, and it was well worth the free trip. would i pay for it normally, nope, not my thing. but still everyone should go check it out, its not something you can understand really untill you actually do it, and dress code should NOT be part of it.
but yeah if u want to go proper, dress nice, shut up, and enjoy the experience.
