In reviewing the Cave Singers’ awesome debut, Invitation Songs, I was hard pressed to come up with any kind of musical comparison for their eerie, weary, Appalachian psychedelic dirge blues. The sound is simultaneously original and timeless, unprecedented and yet rooted in some sort of fantasy fiction history.

This morning I woke up with Led Zeppelin’s “Bron-Yr-Aur Stomp” running through my head and realized that, if anything, that’s the touchstone: the stomp/clap counter-rhythm; the linear, chorusless song structure; Page’s trance-like fingerpicking (a little snazzier than Derek Fudesco’s minimalism). This 1975 concert video even shows Robert Plant sitting on a stool to deliver his vocals, a la the Singers’ Pete Quirk. In both cases, the sound isn’t a direct conduit to forgotten folk music, it’s forgotten folk music as interpreted by rock guys used to volume and drama.

If you can’t tell, I’m totally taken by Invitation Songs, one of the most surprising and enthralling releases this year, and an absolutely stellar debut. The album drops September 25.

In other Led Zeppelin news, Pollstar reports that Robert Plant, Jimmy Page, and John Paul Jones will reunite with John Bonham’s son Jason on drums for one show at London’s O2 on November 26. Tickets cost roughly $250, and proceeds from the show go to the Ahmet Ertegun Education Fund.
