We went to see Hard Fi last night at the BBC Maida Vale/Vegas studios, as part of Zane Lowe's Radio 1 show.
Zane interviewed a member of the audience who described the place as being like a broom cupboard / a school hall...
Hard Fi were great, but the audience participation went about as far as a bit of clapping and nodding of the head, maybe that's because it was early and there isn't a bar at the venue.
