The supergroup consisting of Dave Grohl (Nirvana, Foo Fighters, Queens of the Stone Age), Josh Homme (Queens of the Stone Age, Kyuss, Eagles of Death Metal), and John Paul Jones (duh) is releasing an album next week, BUT, they just put the album up on Youtube. To say the least, it's fantastic, and has amazing bass playing. Here's the link:

Enjoy.
EDIT: Not only does JPJ do some fantastic bass work, but he lends his mandolin, keytar, and piano skills as well.
