Sorry if it's already been discussed deep in another thread, but I'd like to heartily recommend the latest Foo Fighters release - Skin And Bones.
Listened to it on Sunday whilst doing the three S's and it is simply awesome
I'm not very keen on Dave Grohl live - at least what I've heard on telly has been poor, but when they slow things down as in this CD it's really something to behold. I've also got the corresponding DVD to watch - looking forward to it.
Just as a side note, as I have raised the subject of acoustic material - I'd also like to recommend a band that I don't think gets mentioned too often anywhere.
Tesla is their name, and they released an album some years ago called "Five Man Acoustical Jam" - way before MTV Unplugged started. I wouldn't be surprised if it inspired the show !! Hunt it down, along with their electric releases.
