BACK IN THE MID-'00S, Oregon Ballet Theatre recruited Adam Arnold for its ad campaign "Who's Your Dancer?" Photographed by Alicia J. Rose, it profiled OBT dancers wearing clothing designed by Arnold. Since then, Arnold has wanted to costume a ballet, a dream that has been fobbed off, until this week.

Chromatic Quartet is a four-piece program that includes the world premiere of "The Lost Dance," by visiting Canadian choreographer Matjash Mrozewski. When Mrozewski mentioned an interest in having the dancers costumed by a local designer, OBT Artistic Director Christopher Stowell thought of Arnold.

That was a year ago, but until recently Arnold had almost nothing to work with—neither the dance nor the music had been composed, so instead he applied himself to studying Mrozewski's past work, noticing that Mrozewski "has an interest in pieces and clothing and sets that occupy a space out of time. They bring to mind a certain aesthetic, but aren't vintage." It's a description that, as anyone familiar with his work can attest, could be applied to Arnold's own aesthetic.

Arnold was also privy to the development of the score by Owen Belton, beginning with references that Belton and Mrozewski used as a starting point, including pop hits from the Black Keys and Adele, which Arnold—who tends to eschew mainstream music in favor of obscurities—initially blanched at. "Once I start hearing some smoky vocals, I just turn off," he says, laughing at the fact that he had to check his email to even recollect those artists' names. Luckily, what eventually came out of the process "pleasantly surprised" him. "I can hear the references," he says, "but it's very spooky and kind of disco."

The resultant clothing looks like one of Arnold's signature collections, but each piece is altered in some way as a result of the hours he spent developing techniques that allow a huge range of motion. "I approached it from a clothing standpoint rather than a costume one," he says. "The clothing should be supportive of the movement."
