There's an interview with Jack first, and the performance is the last 45 minutes or so of this file.
Jack followed this up with a secret invite-only gig in a "contagious disease clinic" that featured a full immersive performance by the theatre group Punchdrunk. It sounds thoroughly wonderful and I'm sorry I couldn't be there! (They did send me a consolation email with some nice pictures this morning, though.)
His record company, Third Man Records, described it this way:
Last night at midnight in Central London, Jack White played a secret show in the basement of a disused office block, to fans clad entirely in powder blue medical gowns.
The event was a collaboration between Jack and the Punchdrunk Theatre Group who had temporarily transformed the space into the Vescovo & CoClinic for contagious diseases, and had staffed this fake medical facility with dozens of their actors playing the roles of doctors, nurses and orderlies at the time of a disease outbreak.
Drawing on the themes of Jack White's current album, 'Lazaretto', a term used to describe a quarantine island, the experience began with an elaborate online treasure hunt. A spoof medical infomercial from 1949 appeared in the archives of online medical resource The Wellcome Trust, which contained various obtuse clues that led Jack's superfans to a website belonging to the fake medical company, Vescovo & Company. Thousands of fans submitted their details to this website as part of an online screening for a contagious disease. A lucky few progressed through the screening process that lead to them receiving a telephone call from Punchdrunk actors inviting them to an out-of-hours appointment at the Vescovo Clinic. The clinic had been created for this one occasion by Punchdrunk Theatre across multiple floors of a disused building owned by The Vinyl Factory.
On arrival, fans were asked to change in to blue medical gowns before being subjected to a variety of treatments testing in a maze of medical rooms staffed by Punchdrunk actors. Chaos descended as an outbreak alarm was raised and terrified fans were herded into a smoke filled quarantine chamber. Finally a screen was dropped to reveal Jack and band in full medical uniform who proceeded to belt out a thirty minute set before Jack himself succumbed to the mysterious disease. The rock star fell to the ground in a fit of convulsions before being strapped to a stretcher and wheeled off to a waiting ambulance.
Completely missing the point personal note: I've worked with infectious disease (ID) doctors most of my working life and I've never heard them say "contagious disease" but what do I know? (Apparently it refers to diseases which are infectious on close contact - appropriate for a lazaretto, I suppose.)
He's done this kind of show in London before - Halloween at Shoreditch Church.
