Yeah Yeah Yeahs + Black Lips + Jon Spencer Blues Explosion + Mick Harvey + Anika

All Tomorrow's Parties, the promoters best known for their wild leftfield parties in seaside holiday camps,return to London for their third annual I'll Be Your Mirror festival. Headlining the second night are Grizzly Bear, the Brooklyn alt.rock quartet whose last album 'Shields' was a highlight of 2012. They've also curated the rest of the bill, which includes offbeat pop from The Walkmen, Real Estate, itinerant singer-songwriter McCombs and Beach Boys associate Parks, and immersive soundscapes from Tortoise and I Break Horses. Add in DJs, gourmet food stalls, a cinema and even magicians, and you'd be hard pressed to find a better way to spend your Bank Holiday.
