I'm happy to hear that Dave Grohl will -- when he recovers from breaking his leg during a Foo Fighters concert last week -- do another season of his HBO documentary series, "Sonic Highways." I enjoyed last year's trips through the musical histories of major American cities like New Orleans, Chicago, Seattle, Austin, and New York. Grohl did a good job finding local performers and studio owners who'd lived through and contributed to each town's rock and roll lore, and it was fascinating to see him (and the band) develop a new song for each venue, which were then compiled into the "Sonic Highways" album.
If you missed the first season of the TV series, but have HBO Go, you can watch it on demand. No date has been announced for the next one.
