I just had the pleasure of watching these guys play at Panorama Festival in New York. Their show was absolutely jaw-dropping. From the visuals to the audio quality, pretty much everything was perfect.
Alas, no new material was presented at the show. More than two years have passed since Currents was released, so I don't think it's foolish to have hoped. Oh well. At least we can still travel back in time and enjoy gems like "The Less I Know The Better."
