The Foo Fighters (on the Jimmy Fallon show) and "I am a River," the concluding track from Sonic Highways.
And here's the actual album version.
Just binge-watched the complete Sonic Highways documentary series and finally listened to the CD. Short version: Both doc(s) and album are inconsistent -- and "River" is not without its flaws, either, which is to say it's admittedly a tad earnest and a little contrived -- but overall they're both freaking tremendous. And when Tony Visconti's string arrangement kicks in at the end of "River," frankly I'm a goner.
