Off to the 'big smoke'

So I'm making a trip to London tomorrow as there is a few galleries i want to look around - Stolen Space off Brick Lane where works from Dan Witz are being exhibited. Elm Lester's Paintings Rooms have an exhibition featuring Jose Parla's work. I hear also that JR has some HUGE pieces up on Foyles book store just round the corner from Elms Lester, so i got to check that out. The scale of his work never ceases to amaze me.
