Nestled in Hoxton Square is the gallery and book shop of the innovative Dutch digital agency KK Outlet. We stopped in for the opening of Ewen Spencer’s “Three’s a Crowd,” which intimately captures life on tour with the elusive White Stripes. Having followed the band since 2001, from small clubs to larger venues all over the world, Spencer’s photographs capture the quiet, in between moments, of a band on the rise. A beautifully produced book accompanies the show which is on until 28 January.
