Inside the O2 Academy it is dark, very dark, and the smoke machines have created a thick swathe of fog that fills the air. All very fitting as tonight we have the arrival (and only UK date) of the Northern Ghosts tour featuring Uada and co-headliners Tribulation and Gaahls Wyrd. So we can expect a night of melodic black, gothic and extreme metal, plus whatever other sub-genres you could throw in the mix.
