Heard through the grapevine that Optimo are having a couple of parties in a New York on the 17th and 19th of February. The Friday one is in a club called Don Hill's and the Sunday one is venue unconfirmed.
I can't recommend highly enough that any NY dirts take the chance to get along to see Twitch & Wilkes.
