The last time I saw Ulver, almost exactly four years ago, they had only recently begun to exist as a fully functioning live group. That concert at the Arena had something of a rarefied atmosphere, with flickering candles adding to the heavy air of expectation that attended the performance. Since then, though, Ulver have gone the way of seemingly every other once distant and mysterious studio-based outfit, and have begun touring on a regular basis. As a result that sense of occasion was largely missing from their recent show at the Szene, although there was certainly enough taking place onstage to mitigate that absence.

They’re a strange-looking bunch, that’s for sure. Two serious techno types at the front, focused on their various dials and buttons; a dapper Roy Harper lookalike at the keyboard; an energetic guitarist; and a couple of drummers at the back, whom I hardly caught a glimpse of all evening due to my front centre position. But the music they make together is a compelling blend of noise rock, dark isolationism and playful, infectious grooves.

Indeed, it was that grooviness that made the strongest impression on me. The 2010 concert was great, but it was also a touch doomy and portentous, qualities that Ulver seem to have largely shaken off in the meantime in favour of a looser, more improvisatory approach. On this occasion Kristoffer Rygg’s sombre vocals were set off perfectly by insistent percussion, churning ambient textures and Daniel O’Sullivan’s strikingly expressive guitar work. With a succession of sinister back-projected images adding to the overall sense of unease, the music of Ulver is deliciously spare and unsettling: the sound of an unwelcome presence, somewhere close at hand.
