Just got the album by this lot. They are QotSA's Josh Homme, Foo Fighters' Dave Grohl on drums, and Led Zep's John Paul Jones on bass/keyboards.
<self indulgent Supergroup alarm!!>
This is a big rock beast - perhaps even an old fashioned rock dinosaur, but quite agile at times and occasionally surprising.
I'm actually enjoying it - it sounds just like you imagine it would - intelligent-but-dumb driving grungy hard rock with a slight proggy twist, consummately performed, but hardly groundbreaking. It is nice to be reminded what a good bassist JPJ is, and Grohl a fine rock drummer too.
If you like this sort of thing then I'd definately give it a listen.
