Less abrasive than A Blaze In The Northern Sky, the icy keyboards that flow through songs like opener Into The Infinity Of Thoughts put you straight into the darkness that ‘Creeps over the Northern mountains of Norway’, or the madness of the bombastic moments in Cosmic Keys To My Creations And Times. The atmosphere throughout is genuinely masterful, as vast and imposing as the landscape in which this music was formed. Ihsahn once even told Kerrang! that when he was learning guitar, he would get reverb by playing outside and listening to the sound bounce back at him from the neighbouring hills and mountains, adding, “That’s pretty black metal, right?”
And it’s not just in the production – just rich enough to overpower, harsh enough to chill the blood – that achieved this, however. Listening to early versions of I Am The Black Wizards and Cosmic Keys… on 1993’s rough, self-titled EP, you can hear the ambition engrained in these songs’ DNA.
It would be inaccurate to say that In The Nightside Eclipse had a Nevermind effect upon its release. Black metal was still a staunchly underground movement, both by non-commercial intent, and simply because such extreme music doesn’t sell in such quantities. It also came during a truly fecund period, where essential albums like Mayhem’s De Mysteriis Dom Sathanas, Immortal’s Pure Holocaust and Darkthrone’s Under A Funeral Moon would all emerge in a relatively short time. But as time has gone on, it has retained an authority that remains ahead of the pack even now. And always will do.
