Can there really be such a thing as a “secret” band in the Internet age? Maybe if the media is willing to play along. So far, a concerted effort to unmask the members of Denton’s Pyramids has been lacking. And maybe that’s half the fun, especially with music that’s as mysterious as who’s making it.

Reviewers are comparing the noise-rock avatars to Blut Aus Nord, Jesu and other current avant-metal groups you’ve —  er, I’ve — never heard of. So why the fuss? Pyramids’ self-titled debut is full of interesting tensions, as long as you’re not a stickler for such pleasantries as melody. Think Sigur Ros or Tortoise.

Or to grope back decades for reference points, try Brian Eno, The Residents and British shoegazers like My Bloody Valentine. Throw in the sound of highway construction, and you’re almost there. The “songs” mimic movie soundtrack music one second, pile drivers the next. Other kindred souls include Bjork and the Bad Plus.

Who Shot JR has an interview with one Pyramid where little about their identities is revealed. They are said to be unknown in the “Denton music scene” and have shunned live shows. Their underground cred is sealed by notices in Pitchfork and DC 9 at Night.

Spoiler alert: last.fm lists The Autumns’ Matthew Kelly as vocalist and guitarist, and a review in LA Weekly refers to “S Windett’s voice” on album opener “Sleds.” But then again, who are The Autumns and S Windett? Shush. It’s a secret.
