Andy Gill's pick of the Glastonbury festival

Amy Winehouse (Pyramid Stage, Saturday)

For all the obvious reasons – but mostly because she's the pre-eminent vocal interpreter of her era, blessed with gifts that most of the weekend's line-up would give their right hands for.

White Denim (Park Stage, Sunday)

This Texan trio's endlessly involving debut album attempts to redefine the whole indie aesthetic. One of the breakout acts of the year, not to be missed.

Leonard Cohen (Pyramid Stage, Sunday)

Partly because there probably won't be too many further opportunities to catch him and partly to see whether that elegant baritone charm can work its magic as well over a field of people as it does over a theatre audience.

Spiritualized (John Peel Stage, Sunday)

Jason Pierce's return from the brink of death has imbued his music with a new depth and soul. Promises to be the weekend's most moving experience.

Manu Chao (Pyramid Stage, Saturday; Jazz World Stage, Sunday)

The most charismatic crossover act in world music, Manu Chao combines dub-funk grooves laced with oud trills and arabesques, and the natural stage appeal of Charlie Chaplin. A huge talent in a surprisingly slight body.
