Sigur Rós makes beautiful but utterly confounding music. The Reykjavik, Iceland, band's songs often snake through eight to 12 minutes of near-orchestral prog-rock. Lead singer Jon Thor Birgisson has a startlingly high, feminine voice; he also prefers to make an instrument out of his voice, forgoing lyrics in either English or Icelandic and creating his own celestial language of sounds and codes. Even more bizarre, the group chose not to name its latest album or any of its eight soundscapes that one hesitates to call "songs." Press folks refer to it by default as ( ), an allusion to an icon on the album's packaging. You could say it's alien lullaby music. Here's a question: What the hell does it all mean? The answer will disappoint you.
Scheduled to perform with Anima on Friday, April 4. Doors open at 7 p.m. Tickets are $25, $27 on the day of the show. For more information, call 480-966-7715.
