New Yawkers may have noticed a bunch of brightly painted pianos sitting pretty on street corners and parks around town (like little ladies of the night?). These are all part of non-profit Sing for Hope's Pop Up Pianos project in which 88 pianos (coinciding with the number of keys), each decorated by a designer or artist, are put out for passers-by to play for two weeks, after which they're donated to schools. Go to St. Nicholas Park in Harlem to check out the above piano which uses sacred Ndebele-inspired designs from South Africa. If you find yourself at the right time in the right place (ahem, July 1, 6pm, see above for directions) you'll be treated to a free concert by Antibalas frontman Amayo. Afterparty at The Shrine.
