This Warp20 thing is out of control, yo. First there was the shindig at Terminal 5, then a weekend-long film retrospective at the New Museum, and a free Chris Clark-led DJ show at the Financial Center's Winter Garden early this evening. The self-congratulatory celebration closes with a party featuring recent Warp signees: a bespeckled version of Beck (Jamie Lidell), one of the best indie-pop acts to emerge last year (Born Ruffians), and an electro duo obsessed with post-punk (The Hundred in the Hands).
