Old ravers never die: they just blackout.
Proof comes in the form of a bold brand extension from sometime London superclub Ministry of Sound: the "Ultimate Blackout" range of tents.
Designed to help saucer-eyed ravers find some semblance of sleep during the festival season, the two tents feature dense fabrics to shut out the sunlight.
The £50 Sound Crash Pad Dome Tent will keep two people in darkness thanks to a 2000 hydrostatic head. (Nope, I've no idea either.)
Even better, the £70 Speed XT Tent (pictured) offers pop-up assembly, so you don't even have to pitch it before the revelries begin - just throw it to the floor before you blackout. It's got a porch to shelter those muddy wellies/unwanted hangers-on, too.
While they might cut out the light, it's unlikely that they'll help avoid the true tent terror of festival season - the 'oven effect' of sweaty bodies and morning sunlight.
Fittingly, the tents are being sold exclusively through Blacks, and each one comes with five free downloads from the Ministry of Sound music store: we'd suggest 'Eternal Night' over 'The Sun Rising'.
UPDATE: I now have confirmation of what I'd call 'the science bit' if I were on a shampoo ad:
"The MOS speedXT and crash pad have a black flysheet and a black inner tent. This is how the tent stays dark inside, even in bright sunlight, allowing the user to get some sleep during the day. The effect of the shade created inside coupled with the air vents, which draw hot air out of the tent, helpa to keep the tent cool in hot weather."
Which means that, for the first time in over a decade, the Ministry of Sound will actually help you be cool.
