Something for the weekend: Punchdrunk and Fleetwood Mac "Immersive theatre": the dreaded phrase. Nothing inspires me with greater horror, except perhaps "interpretive theatre." For 13 years, however, pioneering "immersive" drama-dance troupe Punchdrunk have been fighting a one-company war to rehabilitate the idea. And they've picked up a surprising amount of followers along the way, with celebrities such as Matt Damon, Stephen Fry and Natalie Portman among the growing thousands in thrall to its masked revels. For the uninitiated, Punchdrunk fill empty buildings with performers and meticulously detailed sets and then let the audience loose. So last Friday, I put aside my preconceptions and headed down to 31 London Street, a former Royal Mail sorting office behind Paddington Station which is now the sprawling set for Punchdrunk's latest show, The Drowned Man: A Hollywood Fable. I wasn't disappointed. Loosely inspired by Woyzeck, Georg Büchner's fragmentary masterpiece about a demented soldier who kills the woman he loves and then drowns himself, the show takes place over four enormous floors, in an eerie Sixties Hollywood film studio where audiences are free to wander around at leisure, occasionally interacting with the cast. And wander around you must, as you take in a creepy old Wild West town, a sinister monochrome dancehall, a sweeping desert and a bar, equipped with its own band, where you can lower the mask you're required to wear and enjoy a nice glass of wine. Punchdrunk is indeed all about getting stuck in. Look, smell and listen: you're plunged into a world so astonishingly textured that you could separate from your friend for the evening and, depending on how curious you've been, report back with a completely different set of experiences. You might not always be able to glean what's going on around you: the plot, in which two intercut melodramas tragically unfold over three hours, is so cryptic a synopsis is handed out on arrival to help steer you in the right direction. But no matter. If you're looking for a trippy, Lynchian few hours, this is £40 well spent. The Drowned Man is running until 29th September, and tickets can be purchased here. Fleetwood Mac UK tour Soft-rock behemoths Fleetwood Mac's eagerly awaited reunion tour kicks off at the London O2 on Tuesday - and the good news is, there are still tickets available here. It's 36 years since the quartet released their seminal 1977 album Rumours, so expect nostalgia to abound as Stevie Nicks and co serenade audiences in London, Birmingham, Manchester, Glasgow and Dublin with the coruscating harmonies and guitar flourishes that have become their signature. Best of the rest... Sweary Scotsman Gordon Ramsay launched his highly anticipated new restaurant, Union Street Café, in Southwark, south-east London, on Monday. Australia, the Royal Academy's exhibition of the country's art, opens on Saturday and runs until December 8. Click here for our critic Alastair Sooke's four-star review. Answering the question, "why are there no New York-style Seventies disco parties in north London?'" is new club night Executive Realness, which attempts to recreate the spirit of classic NYC venues like The Loft or Paradise Garage in cosy Stoke Newington basement club The Waiting Room. The music isn't just stuck in the US though: DJs Jonny Ensall and Joss Bibby offer a business-class get down that covers everything from Brazilian boogie to Nigerian Afrobeat. Entry is £2 (£4 after midnight) from 10pm this Saturday. It's the Barnes Food Fair on Saturday, where more than 80 artisanal food producers will be pitching up in bosky surroundings. There'll be live music all day, as well as demonstrations by Michelin-starred chefs Phil Howard and Theo Randall. Got a hot tip for next weekend?
