With even the greatest bands in the World, it is quite easy to forget just how good they are. It has been six years since Kvelertak last visited this country (Download 2019), eight years since they last played this city (supporting Metallica at the arena) and nine years since we got anything resembling a headline tour. Tonight is very much a case of "Hello! Remember us?" as they grab us by the lapels and forcefully remind us why they were the band on everybody's lips last decade. This evening also, inexplicably, gives us our first opportunity to witness “new” vocalist Ivor Nikolaisen up front and personal. We say “new” but he has actually been in the band since 2018, but as the stats above illustrate these are his first UK headline shows with the band. Replacing a “name” vocalist is always a Herculean task, but when it is in the colossally charismatic shape of Erlend Hjelvik, you would suspect it would be rather a hiding to nothing. However Ivar Nikolaisen sidesteps the need for comparisons by being a completely different school of frontman with his own energy, charisma and style.
