Secret 7" is an annual event that combines music and art for a good cause. They take seven tracks from seven of the best-known musicians around and press each one 100 times to 7" vinyl. Creatives from around the world are then invited to interpret the tracks in their own style for one of the seven tracks, creating one-of-a-kind sleeve for each one. The 700 sleeves are then exhibited and sold, with all money raised being donated to the selected charity. You won't know who created the sleeve, or even which song it's for until you have parted with your cash.
