Arts Desk’s favorite electropop duo Bluebrain is taking to the stars tomorrow evening. Well, not literally, but brothers Ryan and Hays Holladay are bringing their act to Arlington’s David M. Brown Planetarium for a fundraiser for the financially-imperiled facility. The planetarium, which is operated by Arlington Public Schools, was marked for closing earlier this year although Friends of the Arlington Planetarium have scrambled mightily over the past few months to raise more than $240,000 by the end of the year. (So far, according to its fundraising site, total donations are just above $90,000.)

Bluebrain, seen last month kicking off the Artisphere (where Ryan Holladay is a curator) and collaborating with Matthew Hemerlein for a ReadysetDC show in Adams Morgan, will play an improvised — and according to Hays Holladay an uncharacteristically quiet — ambient set at the planetarium tomorrow night for its latest benefit.

“It’s an early evening, more relaxed show,” Hays Holladay told me this afternoon. “Definitely different than our normal live show, which is louder.”

Also out-of-the ordinary for Bluebrain is that while the brothers usually come up with a brilliant, dizzying video accompaniment to their performances, they will be ceding that role to the planetarium’s equipment.

“They can simulate sunset into twilight into nighttime,” Holladay continued. “It’s something we don’t want to mess with. We’re just going to piggy back on their program which is really cool.”

Friday, Nov. 12. At the David M. Brown Planetarium. 1426 N. Quincy Street, Arlington. Doors 6:30 p.m. $15/adults, $5/students.
