Warthur The "covers album" tends not to get a good rap, but anyone who knows anything about Ulver would know full well that they'd take an off-beat approach to the idea. Here, they take a leaf from David Bowie's Pin-Ups and give a highly individual spin to a brace of 1960s psych and garage rock deep cuts.

Just as Bowie gave his selection a glam rock spin in keeping with his musical approach at the time, here Ulver recast the songs they select into a distinct mode of their own - a mixture of psych-aligned proto-prog and gothic darkness, like what might happen if the Doors and the Cure got to jamming.

As the cover art implies with its incorporation of one of the most iconic and harrowing images of the Vietnam War, this reinterpretation with the aid of hindsight teases out the darker aspects of the flower power era - a time when the sunniest pop to ever grace the airwaves was churned out even as a war that traumatised a generation and made the whole world question the innocence and good intentions of US foreign policy raged.

The end result is a classic example of how a distinct and original artistic statement can be put together even if it doesn't wholly constitute original material - plus the individual interpretations of the songs are some great goth-psych stuff on top.
