Here's my favorite (unsung) female shredder: Monica Queen
You Tube serves her very poorly at the moment. Perhaps a little more interest will change this. Some still remember her for lifting 'Lazy Line Painter Jane' (Belle and Sebastian) up to a higher level, but her band (Thrum) are now pretty much forgotten. Sad in my view.
She's still out there, bless her. Not so shreddie, but just as good. The campaign to resurrect the career of Monica Queen (and Thrum) starts here. I wish.
