As the name suggests, 5×15 arranges evenings in which five speakers are each given 15 minutes. Its offering next week at Trinity Buoy Wharf, in London, is devoted to the Thames. On the bill will be the Korean-American artist Ik-Joong Kang, on “Floating Dreams”; London’s best-known psychogeographer, Iain Sinclair, on “River of No Return”; the sculptor Richard Wilson, creator of Slipstream at Heathrow’s Terminal 2, on harnessing the creativity of the river; the playwright (and founder of The Midnight Run) Inua Ellams, on “water stories”; Orlando Seale, front man of The Swell (which Serena Davies of The Daily Telegraph says is “Like Arcade Fire with better lyrics”); and Rachel Lichtenstein, author of Estuary: Out from London to the Sea (see previous post), talking about the people of the Thames. Looks like a great bill.
