In 2018, Pearl released debut album, Sleepless Dreamer, which Rough Trade described as “The best country-pop we’ve heard in years” and Buzzfeed called her “A modern June Carter meets Lana Del Rey.”  With the recent release of the follow up, Magic Mirror, she leans into furthering her own brand of country-disco.

David Ryan Harris


You’ve either got soul or you don’t. David Ryan Harris most definitely does. The singer, songwriter, and multi-instrumentalist has built an impressive catalog of soulful stories that instantly captivate. “Soulfulness comes from telling stories in the most honest and direct way that you can,” he says. “People relate to what you’re saying when you sing from the heart.” That’s exactly what Harris has done throughout his near three-decade career. Whether it be in early bands such as Follow For Now, Brand New Immortals or over the course of six full-length solo albums, he tells stories that resonate. He’s carried this same spirit while producing, writing and/or performing with the likes of John Mayer, Dave Matthews, India.Arie, Cassandra Wilson and Guy Sebastian—with whom he co-wrote the RIAA platinum-certified “Battle Scars.”

Matthew Tilleard

Raye Zaragoza

Raye Zaragoza is a galvanizing presence, a self-assured artist making music to fight for, represent, and celebrate those left too long outside the spotlight. Known for tenacious feminist anthems and fearless protest folk, her stage presence teems with determined morale. As a Japanese-American, Mexican, Indigenous woman, Zaragoza spent much of her early life trying to assimilate with the world around her, to meet punishing standards of beauty synonymous with just one color of skin—and not her own.  This rightful confidence radiates across Woman in Color, Zaragoza’s sophomore album out now on Rebel River Records, her own independent label. The album delivers powerful missives about embracing one’s own identity and discovering the power behind it, all across brisk, emotive, compelling folk melodies. Once deemed “one of the most politically relevant artists in her genre” by Paste Magazine, Raye Zaragoza now offers an intimate exploration of coming into her own, in a country where for many, simply existing is political.
