Having shrunk to a duo within the last year, NYC experimentalists Battles have just released “Titanium 2 Step,” the lead single for the forthcoming long-player Juice B Crypts due out in October via Warp. It’s a frenetic space jam of chaotic funk with Liquid Liquid’s Sal Principato lending sporadic vocal yelps. The band is currently on tour in Europe, hitting the US in early December.
