ITUNES FESTIVAL: Haim + Gabrielle Aplin + more

The three Haim sisters (plus a drummer, no relation) bring their brilliant and breezy West Coast harmonies to the UK to headline the iTunes Festival. They haven't even brought out a debut album yet, but they're already big news thanks to a string of epic, R&B-influenced pop singles – as much Wilson Phillips as Heart or Fleetwood Mac. Turn up early for three support acts: equally breezy beat-popper Dan Croll, groovy Mancunian Bipolar Sunshine and young singer-songwriter Aplin, who's gone from soundtracking John Lewis ads to Number Two on the UK album chart.
