Hands up who's been to see Cirque du Soleil's 'Saltimbanco'...
It's such an amazing show and not what I was expecting at all. A mixture of traditional circus tricks (acrobatics, juggling, trapeze etc), theatre, dance, comedy and music, dramatic costumes, audience participation, it even has it's own language and the whole thing is so precisely choreographed.
For me it had sinister undertones which made it fascinating (there's nothing scarier than a clown in what looks like a plague mask).
It's truely amazing. If you have the chance go and see it.
