Evan Parker in full cry at the old Vortex in Stoke Newington. photographed with a telephoto lens at slow shutter speed. I remember Evan’s pre-Christmas gig a few years ago at the Vortex. Some lunatic booked a large table at the back for a loud office party. Evan’s only introduction was “Good evening ladies and gentlemen, and welcome to an evening of uncompromising free jazz.” Then, unamplified he proceeded to blast the opposition from the room – they left in the first set.
