Women are under-represented in lots of professions, but music and the arts are generally thought to be areas where there is at least a modicum of equality. In rock music, for instance, the battles have been fought -- and largely won -- over gender parity, a plethora of female musicians (guitarists, drummers etc) proving that women can rock just as well as men.
To jump to the conclusion that it's all down to market forces - that young people just don't want to go to clubs anymore - is ill-informed and misleading. Legendary London venues such as Turnmills, The Cross, Cable, The End and more all closed due to the effects of gentrification and the siren call of property developers - not lack of demand.
I get asked a lot why I still go to nightclubs even though I'm 35 and attached. Er, for the music, of course. I've never been one to view a night out as anything other than a chance to experience a vibe, and get excited about musical trends and the ongoing expansion of dance music, in its many forms.
