Anthony Green of Circa Survive recently performed a lengthy acoustic set at NYC's House of Vans. This video totals at one hour, and we'll let you know right now that it's worth making it to the end. As always, Green's unique, high-pitched vocals draw in an audience like few others -- and he's a genuinely cool guy. Watch how he makes a point to allow for audience vocal take-over in the first song and breaks between songs to joke around. It's solid acoustic strumming, as well. Check it out and don't forget to pre-order your tickets for Green's upcoming national tour with The Dear Hunter.
