Three time winner in the 2012 German Blues Awards and a Finalist in this years ‘German Blues Challenge’, the star of Jessy Martens would seem to be on the rise. But how good is a German Blues Award winner? On the evidence of her appearance at the Harmonie on Thursday, very good indeed. If you’re reading this in mainland Europe get to a concert, and if you’re in Britain, America or Australia do yourself a favour and get a copy of the new CD. This girl has a big future!
