An Idaho native, pianist/composer Deidre Rodman moved to New York in 1997 after receiving a Master's Degree in Jazz Studies from the University of North Texas. She found work playing for the Big Apple Circus, and spent her free time going out to hear all the music she could. She immediately found musical synchronicity with a number of players from the downtown scene, including Roy Nathanson of the Jazz Passengers.

Nathanson and Rodman co-hosted a weekly band night at the Knitting Factory for close to a year. She then played on the album and touring production of his critically-acclaimed Fire at Keaton's Bar and Grill, which featured vocalists Elvis Costello, Debbie Harry, and Darius de Haas. The show was revived for a benefit at St. Ann's Warehouse in Brooklyn and featured Lou Reed, Laurie Anderson, Antony, and Dan Zanes, among others. She and Nathanson continued to collaborate on projects such as the 10-piece Alphabet Lounge Big Band.

De Haas sought her musical direction, piano prowess and arranging skills for his Lincoln Center premiere of So This is Love: Variations on Strayhorn, which the New York Times hailed as “extraordinary”. Jazz Times called Daydream, the follow-up recording, "one of the finest Strayhorn salutes ever captured on disc".

Meanwhile, Rodman collaborated with Debbie Harry on a version of the song "All the Way" for the soundtrack of Pie in the Sky: The Brigid Berlin Story, which won a coveted AFI Fest Documentary Award. Elvis Costello, with whom Rodman appeared on The Conan O’Brien Show and Live with Regis, has deemed her “a wonderful pianist and delicate composer with a truly unique voice”.

Rodman formed her jazz quintet in 1999, recruiting members Tony Malaby on tenor saxophone, Russ Johnson on trumpet, Bob Bowen on bass, and Mark Ferber on drums. Their first Sunnyside recording, Sun is Us, was released in August 2001 to enthusiastic reviews, and was followed by a successful first tour. Also featured on that recording: drummer Ari Hoenig and alto saxophonist Loren Stillman. On their next release, Simple Stories, the quintet was joined by vocalist Luciana Souza and The Neighborhood School Children’s Choir, with the composer’s vocals and melodica rounding out the mix. The Washington Post described it as "crisp and sweet as a bite out of a Fuji apple". She added to the Sunnyside catalogue with Twin Falls, a duo record with renowned jazz electric bassist Steve Swallow.

It is well-known among her friends that Deidre likes Christmas, so naturally she recorded a Christmas single for Sunnyside, Christmastime in New York, featuring Jamie Leonhart and Gabriel Gordon on vocals.

Deidre has performed with many other notable musicians including Natalie Merchant, Clare Muldaur Manchon, Greta Gertler, Lee Feldman, Nancy King, Mary McBride, and Mike Viola.

A project very close to Deidre's heart is The Lascivious Biddies, a genre-defying all-female quartet which performs originals and standards-to-be.
