Bards and Guitars from backyard of Mars

I envisaged all kinds of heroes and monsters and wizards having guitar duels on planet Psychon. Most of these instruments could be changed  to others. While im not really into rock, I do appreciate its role in much of my favorite 70s SF. Hawkwind I personally like. Other stuff like jethro tull and king crimson, 60s psyche and sitar rock wouldn't hurt either.
