What do you get when you gather representatives from two of the greatest crews ever to rep the East–or any–coast together on one record? You get Union Square, the latest promo single from newly-formed Wu-Tang/D-Block collective Wu-Block. Here, an unknown beatsmith’s gritty production sets the mood as Ghostface Killah trades tightly-wound bars with Sheek Louch. Wu-Block, a self-titled album, is tentatively set for a mid-August release on eOne.
