Last year to kick off their tour, folkie-rock band Edward Sharpe & the Magnetic Zeros played 5-nights at the Old Vic Tunnels in London. They filled those 5 nights with as explosive a visual and auditory treat as they could with performance art, psychedelic light shows and film screenings (Holy Mountain, Renegade, etc..), experimental dance and of course music. It was pitched as a "360 degrees experience" with this happening in different rooms and on every turn. A wild, wild West in the middle of London. Looked cool to me. As expected all 5-nights sold out.
The folks at the Old Vic Tunnels created a short 10-min documentary capturing the behind-the-scenes of this event.
