HOT: Secret Cinema, Shepherds Bush Empire, 56 Shepherds Bush Green W12 8QE

Saturday night - opera; Sunday night - heavy metal.

Secret Cinema has been on my London to-do list for a while, although it no longer has its underground feel because it's been written up in every newspaper and listings magazine. The queue snaking around Shepherds Bush Empire on a Sunday night was testament to the popularity of the concept.

Basically, you buy a ticket for a mystery film, at a mystery destination. A few days before, you're given your location and the film is only revealed on the night. There are clues along the way though - we were asked to dress in 80s rock (lots of shiny leggings on men, big teased hair, fur, leather and blow up guitars) and the ticket categories were 'Rock God' and 'Shady Promoters'. Hmmm....'This is Spinal Tap' was my bet, until I spotted a new movie poster in the tube.....

Anvil! The Story of Anvil is a documentary (no, not a mockumentary Huy) about an 80s Canadian heavy metal band that never really made it, despite the likes of Metallica, Anthrax and Slayer citing their influential music. Now in their 50s, they're still together and trying again to get a break. It's unintentionally funny, poignant and heartwarming as you follow their quest for a last chance at fame.

And then.....the special guests of the event were Anvil, live on stage! It was fantastic, even though it wasn't my sort of music. The crowd cheered them on as they thrashed their guitars, swung their sweaty hair around and RAWKED like old rockers do.
