From the moment Carly Rae Jepsen arrived at NPR HQ for her Tiny Desk concert, she brought an obvious sense of joy.

Punk rock might be a relatively young genre, but the legend of its history has already become more or less solidified.

Ask what makes punk punk and you'll probably get a story that starts in 1970s London, or maybe New York; you'll get The Sex Pistols, The Ramones or The Clash; counterculture, anti-establishment and leather jackets.

After Camp Cope's second song at the Tiny Desk, singer Georgia "Maq" McDonald let out a tiny laugh. "We've never done this before — we've never been quiet," she said. "Not once in our entire lives!" Bassist Kelly-Dawn Hellmrich joked that it was perhaps a "good lesson" to "rock out in your mind." ("Thinking," Maq clarified.)

As Japanese Breakfast, Michelle Zauner writes sparkling, opulent dream pop about grief and love (and, occasionally, robots). After releasing its debut album, Psychopomp last year, the band returned with this year's stunning Soft Sounds From Another Planet. Where Psychopomp, written in the immediate aftermath of the death of Zauner's mother, zeroed in on the experience of Zauner's grief, Soft Sounds widens her aperture, featuring paeans to her coping mechanisms, ruminations on crooked relationship dynamics and said sci-fi robot fantasy.
