A friend who lives in the Barbican was raving to me about the exhibition currently in the Curve gallery there, in which a cheery flock of finches play electric guitars. I looked incredulous, so he sent me the link to this video. It may not be Art, but it’s clever and amusing. The strange thing is that the birds don’t seem to be upset by the noise. Come to think of it, they’re just like my teenage kids in that respect.
