Lost Lectures take thrilling talks out of the boring old corporate conference centre and launch them into beautiful (and very secretive) spaces infused with imagination. Tonight, they're holding their most hedonistic night yet; think glamour and gambling, dancing and drinking, jazz and razzmatazz. As ever, there'll be an eclectic mix of world-class speakers emerging from the decadent haze, including award-winning transgender activist Paris Lee, SENS' chief science officer Aubrey de Grey, and Cassette Boy – the YouTube comedy electro duo. Oh, and there'll be live music from Alabama 3 too. See you at the bar. General admission. Over 18s only. Dress code: your gladdest of rags. Secret location revealed upon booking.
