Colourscape’s labyrinth of polychromatic tunnels is returning to Clapham Common once more this September. Never been? Just wander around its big inflatable labyrinth to see what musicians you can find inside. You might happen upon a flautist, a classical guitarist or maybe some bloke playing an actual conch. Who knows!? Those kaleidoscopic innards are designed to surprise. One of the few upsides of the post-covid era is that you have to pre-book, doing away with the long Colourscape queues of yore.
