Some bands opt to simply sprinkle their tunes with keys, while others go all-in—and Brooklyn trio Au Revoir Simone sticks to the latter. Formed in 2003, the infectious dream-pop act (longtime friends Erika Forster, Annie Hart, and Heather D’Angel) is 100 percent keyboards, with each member boasting her own vintage setup. But while the outfit’s airy electro-pop is driven by shimmering synths, it’s also supported by gorgeous, layered harmonies and simple drum machine beats. This breezy formula offers up an enchanting atmospheric quality that has attracted some big-name admirers, including Broken Bells and David Lynch. Packed with playful, futuristic chords, Au Revoir Simone’s latest record, 2013’s Move in Spectrums, sounds less fragile than the group’s previous releases. Where the trio’s debut, 2005’s Verses of Comfort, Assurance & Salvation, is all silky vocals and hushed keys, Move in Spectrums comes to life with deeper synths and dynamic harmonies. Au Revoir Simone performs with Little Daylight and the Lower 48 at 8 p.m. at Rock & Roll Hotel, 1353 H St. NE. $14. (202) 388-7625. rockandrollhoteldc.com.
