Noble and Silver, Pleasance Above

Noble and Silver like to start their show in the middle and finish it somewhere near the beginning.

Noble and Silver like to start their show in the middle and finish it somewhere near the beginning. They put questions to audience members which are answered by recorded voice-overs, and talk to each other through one, two and sometimes three television screens. They lead us up all manner of blind alleys – a man is given a goldfish bowl to hold on his lap, though nothing comes of it.

What's more, they repeatedly wrong-foot us, making out the gadgetry's gone wrong. "Are we out of sync?" asks Noble on one screen. "Yeah sorry, I must have been talking too fast," answers Silver from another. These are clever boys with very clever toys.

Their show is ambitious and intriguing, but there's one big drawback. It's not funny. Sure, you can gasp at their technical skills, but then you'd probably do the same if you watched a computer programmer at work.

After their hour is up, we are presented with footage of us watching the show at the beginning – or is that the end? Who knows? Noble and Silver's show may be the most inventive at the Fringe, but it just doesn't make you laugh, and that surely is the point.
