Sadly Astoria was closed and then bulldozed to make way for the new Crossrail station. It was a great nightclub and mid-sized rock live venue. I saw so many great bands there.
I used to love dancing. I could go for hours. I went to a variety of student nights, indie, metal, goth, rave, techno nights in the towns I lived in and the mighty Slimelight in London. The Slimelight was so big there were plenty of nooks and crannies for goths to plot and connive against their enemies or greet and hug their friends. More adventurous behaviours occurred in the uni-sex toilets. The place was pumped full of dry ice and everyone looked like beautiful dark elves. It was glorious. It is still going so I hope that some people are still experiencing a magical world there as well as having a bloody good dance.
Towards the end of the crusty-techno era I also used to go to the Whirlygig in Camden. Towards the end of the night they would bring out a silk parachute and we'd all sit underneath whilst volunteers waved it up and down over us. Gentle chillout music and flashing lights made us all feel extremely mellow and happy whether people had taken drugs or not.
I kind of miss clubs full of people on E. I have never been hugged by so many complete strangers in my life and when people stopped taking E and went back to drinking alcohol fights started breaking out and people vomited on the dancefloor which is just eww. I was the designated 'straight mate' and I would look after any one having a bad time on drugs or alcohol but wasn't needed more than once or twice, thankfully.
Unfortunately my old mates all settled down, had families and stopped going. I grew fat, single and old and couldn't face walking around London that late at night on my own. I have to dance in my living room or shuffle gently on tube platforms (embarrassing) instead.
I think that clubs catering towards an alternative culture are still around if you know where to look. However, there are probably fewer of them because there is more competition for your time and money. Also the music scene is very fractured and dispersed. It is hard to imagine a group of 20 people all loving the same music going over to the nearest city on a bus together although I hope I am wrong.
I am not particularly sorry that the high street flesh palaces are going though. It used to be dangerous walking past them if you looked different. They often needed the police calling at the end of the night too.
TL: DR - Sorry for the essay. In short: Good times. I'm sad if it is going but other things are taking their place which I hope will produce their own fond reminiscences in later life.
