So I went to the preview night of Secret 7 tonight down in Hipster Heaven (Shoreditch). I went last year to it in Summerset House too.
Premise is that seven tracks from some well known musicians, then each song is pressed 100 times to 7” vinyl. Then they invite creatives from around the world to interpret the tracks in their own style for every 7”. There are 700 sleeves which are on show for a bit then can be bought at £50 a pop. Money goes to charity.
The secret is you don't know who created the sleeve or which song you have. I know who designed 3 of the sleeves this year and could hazard a guess at quite a few of the songs as they're blatantly on the sleeve (Imagine John Lennon - loads of spectacles on sleeves). But you could end up with a piece of art. Check it out if you are around that way :)
