IX Equilibrium

IX Equilibrium is the third studio album by the Norwegian black metal band Emperor. It was released on March 15, 1999, in Europe and on April 27, 1999, in the US through Candlelight Records.

Reception
Eduardo Rivadavia of AllMusic describes the album as a "sonic onslaught of nearly impenetrable proportions". He noted that drummer Trym "doesn't so much keep time as pummel his kit incessantly", while guitarists Ihsahn and Samoth "contribute an equally oppressive wall of sound laced with keyboard textures so demonic they were seemingly concocted by the great horned one himself." He concluded, "Far from a masterpiece, but hardly a stinker either, IX Equilibrium falls quite short of the group's earlier albums through sheer lack of diversity, and will prove indigestible to all but the most committed black metal fans."

In 2021, it was named one of the 20 best metal albums of 1999 by Metal Hammer magazine. In 2023, Rolling Stone ranked the album's opening track, "Curse You All Men!", Number Forty-two on their list of "The 100 Greatest Heavy Metal Songs"
