I am sure there is a link between the difficulties that prog rockers have in attracting female followers, the absence of female singers and the use of taped vocals. I recall an interview in the recent BBC doco about prog rock where a prog rock band lamented their lack of female fans. I can’t find it now and I am sure its on this blog! When I track it down I will post it.
I not sure where the practice of havingbandnameswithoutspaces came from.
