I'm not sure exactly when this would have been but assume that it was in the 1990's and post start of her recording career.
What I find strange is that,to my knowledge,not one single person has ever made any public comment about having been taught by Stina Nordenstam......cue
I can only think that possibly teaching under an assumed name and without her trademark 'Stina' disguise,no one has ever realised who their teacher actually was.
Any thoughts?
