There's a rather splendid festival going on in London on 10th and 11th August featuring, among others, Reg Meuross, Grace Petrie, Holy Moly and the Crackers, Will Kaufman and the India Electric Company.
It will all be happening in Harrow and should be a great weekend.

Be there or be a right-angled rhombus!
