Kanye West at Glastonbury 2015

Given the choice between these two spectacles for a festival headline set, which would you prefer? On the one hand, a perfectly likeable big rock band, with their plaid shirts, rolling out the same set they've been squelching round the world for ages, full of songs you know, though not necessarily that many you love, unless you're a hardcore fan. Or, on the other, the world's most mercurial and unpredictable pop star, a man convinced of his own genius and prone to gestures so grand they rather take the breath away. (www.theguardian.com)
