Adams, whose musical work includes classical composition and who previously worked as a NASA technician, formed this collective to present her ambitious new songs with a rich palette of instrumental colors.

Bob Boilen of National Public Radio’s “All Songs Considered” calls Arc Iris’ music “somewhat cabaret, somewhat orchestral folk, a bit of show tune and jazz band.”

A reviewer for The Deli online magazine wrote that the group “had everything you could want in a live performance — intense energy, appreciation for performing and incredible talent . . . [They are] something akin to a soul/folk/jazz amalgamation.”

Based in Providence, R.I., the band includes keyboardist Zach Tenorio-Miller, trumpeter Mike Irwin, drummer Ray Belli, bassist Max Johnson and singer-flutist Nora Fox.

Arc Iris’ debut album will be released in early 2014. Their cover of Fiona Apple’s “Every Single Night” can be viewed on the website of the peace advocacy organization The Voice Project.

Adams performed with the critically acclaimed indie folk band The Low Anthem from 2007 until 2012.
