Moments of unexpected magic are the Newport Folk Festival's calling card. The festival typically sells out well before its lineup is even announced — but the official lineup is more of a rough guideline, anyway, since the weekend is peppered every year with surprise performances and collaborations.

It's finally official: Beyoncé Giselle Knowles-Carter gave birth to twins in June, and early Friday morning, Sir Carter and Rumi made their official debut on Instagram.

Beyoncé's caption reads, "Sir Carter and Rumi 1 month today."

As of 6:45 a.m. ET, the photo had already surpassed 4.5 million likes on the social platform.

Adele is again suffering the effects of damage to her vocal cords, she announced in a Facebook post Friday night. As a result, she canceled the final two shows of her world tour. The performances were to take place at London's Wembley Stadium on Saturday and Sunday evenings, and would have capped off a four-date run there.

When you're a group that's performed together for more than seven decades, it might be a daunting task to keep crafting music that feels fresh. No doubt that hill is even harder to climb when you're working within a tradition like gospel, with its well-loved, and well-worn, harmonic and lyrical conventions. Yet the singers who make up Blind Boys of Alabama have always risen to the challenge with utter grace — and the group's forthcoming album, Almost Home, places a capstone on that history.

This week, Philadelphia's WXPN and World Cafe Live play host to the NON-COMMvention, an annual gathering of noncommercial music radio station staffers and industry pros. The highlight: three evenings full of performances by some of public radio's favorite artists. This year's featured performers include Ani DiFranco, Blondie, Chicano Batman, Pixies, Laura Marling, Benjamin Booker, Real Estate, Hurray For The Riff Raff and more.

We're well past the halfway point of the music portion of South by Southwest, and things are starting to wind down in Austin. But the indefatigable All Songs Considered team (well, mostly Bob Boilen) is still raring to go. Bob, Robin Hilton, Stephen Thompson and Colorado Public Radio's Jessi Whitten convened on an Austin street corner Friday night to recap what they'd seen that day.

Aretha Franklin performed "The Star-Spangled Banner" at the Thanksgiving Day football game between the Detroit Lions and the Minnesota Vikings Thursday afternoon. And, as, the Queen of Soul usually does, she stole the show.

More than a year ago, the world first heard the official cast recording of the most successful Broadway musical in recent memory. The album would ultimately go double-platinum and top Billboard's rap chart, owing in part to fired-up fans hitting repeat, memorizing lyrics and absorbing the show's richly textured world.

Soul singer Charles Bradley is battling stomach cancer and has canceled several tour dates, according to a statement posted on his official Facebook page Tuesday.

The 67-year-old singer issued a statement saying he's determined to come back stronger:

"I'm getting the best medical care and we are all extremely optimistic. I will fight through this like I've fought through the many other obstacles in my life.

For weeks, Bon Iver fans have been tantalized by cryptic imagery, pop-up murals and a symbol-heavy track list that would make any copy editor shudder. Now, the band's long-awaited third album, 22, A Million -- its first in five years — is finally available.

There was barely a cloud in the sky all weekend at the 2016 Newport Folk Festival this past weekend. But the uninterrupted stretch of three gloriously sunny days wasn't the only stroke of good fortune festivalgoers encountered. Each day at Fort Adams State Park in Newport, R.I., was filled with surprise guests and moments of serendipity.
