My mate had a penchant for indie/folky stuff - Frank Turner, Beans on Toast, Will Varley, that kind of thing.
He phones me up and says "do you want to come and see Emily Autumn? She plays the violin." I wasn't fussed but with a name like that and knowing his tastes I thought it'd be nice to go along and sit supping a few ales while tapping my foot to some folk fiddle.
Sadly my mate also had a hugely alt/goth tendency in his teens. Emily Autumn is an almost goth/bulesque-lite performer who plays metal with electric violin solos. The majority of the audience were gothed up try-hard teenagers being escorted by their parents.
Worse still, he convinced me to go to the afterparty at nearby cyber-goth club "Slimelight" in Islington. Even worse still, being the late 00s I was dressed in classic, slightly vintage-y indie getup of jeans and a tshirt. In a cybergoth club full of people approaching 10 years younger than me.
And even even worse still, turns out there was no afterparty.
He still owes me BIG time for that night!
