On this week's +1 podcast, we go to Nashville where host Bob Boilen has been making new discoveries at the Americana Music Festival, and attended the Americana Music Awards ceremony. Boilen chats with co-host Robin Hilton about this year's three biggest winners: Lucinda Williams, Sturgill Simpson and Shakey Graves.

We're all gonna die...someday. And if there's mass extinction, what's left of humanity will face nature's wrath, stored in centuries of environmental abuse and neglect. With its second album Litany, Dead to a Dying World plays the soothsayer of the agricultural apocalypse, reaped in a searing and gorgeous vision of crust-punk, doom- and black-metal, with a viola's sorrowful folk melodies stringing it all together.

Kevin Sylvester says that when most people see a 6-foot-2-inch, 260-pound black man, they don't expect him to also be a classically trained violinist. A recent exchange with a woman in an elevator, when he happened to have his instrument with him in its case, drove that point home.

Rock fans who are going to Metallica's concert in Quebec City Wednesday will see an unusual sight: a 48-foot tanker truck filled with Metallica-branded beer. Made at the Labatt facility, the beer is to commemorate the band as it opens a large new venue, the Centre Vidéotron.

The Centre Vidéotron says:

"Budweiser has partnered with legendary rock band Metallica to channel the brute force of this historic show and be inspired by its vibrations, its energy and its decibels to create a beer in the image of the power of rock."

You can be sad, but you don't have to be whiny. New Orleans' Woozy has a whole lot of feelings, but also a whole lot of not giving a damn. This appears to be the trio's M.O. on Blistered, its debut album after a few EPs and split releases. "Gilding The Lily" sounds like a Rainer Maria 45 spinning off-center; it's wobbly and weird, with a twin-guitar-and-vocal interplay that hesitates and jolts forward without missing a beat.

NPR Music is in Nashville all this week for the 16th annual AmericanaFest. So the newest episode of All Songs Considered offers a big bundle of music from some of the acts who are playing the festival that the team is most excited to see. Before leaving D.C., Bob called up NPR Music's Ann Powers and NPR Music contributor Jewly Hight in Music City to talk about what Americana means, and who its newest and most promising voices are.
