I saw Augustines in the Liquid Rooms a couple years back, thought it was a good venue.......decent acoustics.
I saw Gaslight Anthem at the Picture House few years ago now......arite venue, nae the best nae the worst.
I do like the Usher Hall, it has proper character but I've found the acoustics can be hit or miss.
And dinna get me started on the price o' the swally...................
