Fiona,
I'm told The Durbs are playing alongside my DMcF electric folk-rock band on the Sat aft - free to everyone! - in 'The Light' right in the City Centre.
The evening concert (where we are on with Toms Napper/Bliss) will be our 'acoustic' band - just to make it clear which event features which band!
The venue for that one is on the link above I believe.
Cheers - Duncan
