Ah, he’s back at last. Mr O. Our very own Martin. The man with the dancing voice from eastern Switzerland always comes to see us whenever he has a new show. And every time, it knocks our socks off and makes us book him in again straight away for the next one. This is his fourth show, entitled "o solo io". And while it is strictly true that it’s just him, the title neglects to mention the appearance of a well-tempered e-piano, a five-string violin and Martin’s now legendary loop symphonium. He also fails to mention the fact that with these instruments, it’s as if he’s on stage with an entire orchestra and all sorts of different bands. But we understand. "o noi tutti" is nowhere near as sexy a title.
