Live In Concert from NPR's All Songs Considered Folgen

Mountain Man is significantly less burly than its name suggests: Founded at Bennington College in Vermont, the mostly a cappella trio of Molly Sarle, Amelia Meath and Alexandra Sauser-Monnig weaves its voices into a stark, reverent and unadorned sound that can be hauntingly beautiful. Tours with Jonsi and The Decemberists helped put the group on the map last year — as did a spot at the Glastonbury Festival, which preceded the release of Mountain Man's debut album — and it's just followed that breakthrough with a live set called Live at the Wiltern. Mountain Man brings its gorgeous three-part harmonies to the 2011 Newport Folk Festival in Newport, R.I.

It almost goes without saying that Pokey LaFarge is a man out of time: With his slicked-back hair and vintage clothing, he looks like a grown-up street urchin from early in the previous century. His music matches his look: Recorded with his band The South City Three, the new Middle of Everywhere could have emerged from a decades-old field recording, even as it exudes modern whiz-bang energy. (It's no surprise that the man is putting out his own 78 RPM record.) LaFarge and his players put on a tremendously tight live show at the 2011 Newport Folk Festival in Newport, R.I., the result of years spent busking and wandering.

One of the most demented and infectious live bands in the world, Gogol Bordello assembles something approximating an Eastern European punk-rock circus, suitable for non-stop movement and hearty sing-alongs. Look for the band to showcase songs from 2010's Rick Rubin-produced Trans-Continental Hustle when it plays the 2011 Newport Folk Festival in Newport, R.I., but don't be surprised by the abundant surprises.
