I love how Dave Grohl’s answer to “what should we do with this song?” appears to always be “Let’s add another guitar!”

Flipness aside, I have the feeling we’re watching something truly awesome as Grohl continues to promote his Sound City documentary. Not only is he obviously having a blast playing with all these legendary musicians and sharing his passion for this place where so much great music was made, but I have to believe there’s lots of goodwill that’s spilling over from the live appearances to the film itself. It’s cross-media story-telling in a very pure fashion.

Watch this video for the wordless “Mantra” from the film’s soundtrack and see what a great musician Grohl really is. The song’s progression from one segment to the next is seamless and marked most notably by changes in how he plays the bass drum part.
