I generally like Foo Fighters best when Dave Grohl is scream-singing about anger, pain, and persistence in the face of adversity. However, I would eventually get bored with a band that stuck solely to that kind of material, and thankfully Foo Fighters is much more than that. They released "Walk" a couple years after I finally felt as though I had fully recovered from my separation from my first wife, but that didn't stop me from reveling in its embrace of recovery, finding yourself again, and moving forward (yeah, there's an element of the persistence in the face of adversity and screaming in the song too, but it's just as elements, not the primary drivers). It's one of those songs that demands that I turn the volume to 11 when it starts playing.
I don't quite love the video the same way, but I am really amused at the clear allusion to Fallen, starring Michael Douglas.
