Be sure to check out Soundboard for more concert listings for the week ahead, and read on to see what Reader critic Peter Margasak has recommended for the next few days.

“Julianna Barwick has developed a dazzling aesthetic, layering and looping gossamer wordless singing to create an ethereal sound world whose drifting constellations get their heft from gently turbulent vocal harmonies,” Margasak writes. On her new Nepenthe (Dead Oceans) Barwick broadens her approach by teaming up with Icelandic producer and Sigur Ros collaborator Alex Somers, string ensemble Amiina, and members of Mum. “She developed the songs in a studio, and unsurprisingly her cohorts impart a bit of the woozy, meditative splendor that’s characteristic of Iceland’s more expansive pop; on some songs Barwick’s voice gets lost in the floating strings and eerie drift of the Teen Girl Choir (aka the women in Mum who sing on the record). On ‘One Half’ and ‘Forever’ Barwick delivers clearly intelligible English-language lyrics and shapes discrete melodies, both novelties for her, and overall she achieves a satisfying fusion of her own inventions with the new context provided by her collaborators.” Sigur Ros headlines.
