Brian May the living leyend detailing his gear and showing his Red Special and picking technique
Brian May's iconic self build guitar "Red Special" must be a world heritage, something completely invaluable, the best example of what it means I've read it in this analogy:
"The Red Special is the equivalent of someone dreaming of being a racing driver, building a car at home with their Dad, and then going on to win the F1 world championship in it."
PD: May is a living legend!
