ITUNES FESTIVAL: Jack Johnson + Bahamas

Hawaiian surfer and singer-songwriter Johnson catches a wave to London tonight to perform his light-as-a-feather acoustica to an audience of gap-year tragedies and dinner party hosts at the iTunes Festival. With his wistful, gentle ditties about taking life easy, getting in tune with nature, hooking up, getting dumped and making banana pancakes, Johnson isn't to everyone's taste – but by the time September rolls around his sleepy pop might be just the warm musical breeze you need to round off the summer. Johnson is supported by Bahamas, who is – surprise, surprise – a gentle singer-songwritery type, but who is from the distinctly un-tropical climes of Canada.
