For the past year, Luke Wyland of AU has worked closely with the students in the Camas High School Choir. He's taught them the ins and outs of putting on a show, from booking and promoting the event to running sound, and has also been rehearsing a new piece of music with the choir. All of their combined efforts will come to fruition this Friday at Yale Union when the new composition will be presented to the public, complete with the promise of "earth-shattering harmonies," according to Maddie Bertalot and Andrew Henson's press release. It wouldn't take much to get our attention for this show, as it also marks Wyland and his AU bandmate Dana Valatka's return to a Portland stage. They make the kind of impassioned, powerful art-pop that floods the senses and empowers the soul. ROBERT HAM Also see My, What a Busy Week!
