Live In Concert from NPR's All Songs Considered

Closing the day at Folk Festival 50, legendary folksinger Pete Seeger and his son, Tao Rodriguez Seeger, led a hootenanny with some of their closest friends and musicians, including members of The Decemberists and Fleet Foxes.

In the midst of pouring rain, nothing could stop the Newport audience from singing even louder at the Sunday night singalong. Pete Seeger and his grandson, Tao Rodriguez, led the festivities with Joan Baez, Ben Jaffe and members of Balfa Toujours.

Colin Meloy and his crew led the crowd in a singalong of "Sons and Daughters."

The Avett Brothers stomped and hollered high-energy songs from its new album at Newport Folk.

It's been a number of years since Gillian Welch has put out a new album or regularly performed, but she's a regular fixture at Newport no matter what. With David Rawlings, they treated fans to many Welch classics, plus threw in a cover of Jefferson Airplane's "White Rabbit."

In this charming performance at the NPR Music offices, Siskind performs two of the highlights from 'Say It Louder' before closing with a requested "Lovin's for Fools." Each song finds her concocting a heady cocktail of tender beauty and winsome regret, while employing a voice that's at once honeyed and raw.

A lot of talented artists pass by Bob Boilen's desk. But this was the first time that NPR Music was serenaded by a trumpet, trombone, French horn, tuba and truncated drum kit playing a Rufus Wainwright cover (and several clever originals) in rich, soulful polyphony. Dave Douglas Brass Ecstasy plays music from his new album 'Spirit Moves.'

It's a high compliment to suggest that these three Bill Callahan songs may well implant themselves in your brain, lay eggs and sprout horrifically disturbing dreams at that point when you're banging on the snooze alarm in a state of anguished early-morning half-sleep. Hear and watch Callahan perform at the NPR Music offices.

After spending nearly 20 years delivering crunchy, underground guitar rock for a major label, Sonic Youth has returned to its indie roots for its 16th studio album, The Eternal. Out now on Matador Records, Sonic Youth's latest effort is among the band's finest, with a fuzzy, tightly orchestrated mix of psych-punk rock and noisy jams. The band showcased the album in a full concert, recorded live from Washington, D.C.'s 9:30 Club July 7.

If you see Canadian singer-songwriter Julie Doiron perform live, you'll hear a good deal of distorted guitars and intense drumming. Well, at least when she's not performing at the NPR Music offices. It took her a few takes, but we wound up with a bare, stark and memorable set at the Tiny Desk.
