Electric Picnic: London Grammar - perfectly judged set

London Grammar, youngsters with old souls, proclaim that this is the loudest response they’ve ever had at a festival show. The crowd expands beyond the fringes of the tent and cheers in unison and appreciation.

What a difference a year makes. For an act that performed to a smattering of people at Longitude last year, London Grammar are now stars. A perfectly judged set of lo-fi, minimal and emotional tracks soars. You'd hope Portishead were listening somewhere on site, if only to see how far and beautifully their influence has stretched.

In three words: Stunning, soulful, magic.
