Charlotte Ann Martin (born October 31, 1976) is an American singer-songwriter and musician who performs predominantly on the piano.

[3] She graduated from Eastern Illinois University in 1998 with a bachelor's degree in vocal performance,[4][5] majoring in opera.

[citation needed] Following the birth of her first child, Martin suffered from intercostal neuralgia that left her incapacitated for the better part of a year, causing lengthy delays to the writing and recording process of her album Dancing on Needles.

Her first foray into songwriting came in the form of Mystery, Magic & Seeds (1998), an album Martin wrote as a result of a friend's death, which she now considers juvenilia, but which is available for download from archive.org.

Her second album, One Girl Army, remained unreleased, though an EP of the same name containing a few selections from the full-length record was published independently in 2000, and Martin still performs some of its content live.

In 2002, Martin independently released a limited-edition EP containing eight tracks, called Test-Drive Songs, which is now out of print but still available for download on her official website.

Martin co-wrote and contributed vocals to "Glass Breaker", a song by the Crystal Method, included on the soundtrack to the 2005 romantic drama film London.

Martin co-wrote and contributed vocals to the song "Sweet Things" on Tiësto's 2007 album, Elements of Life.

She also co-wrote and contributed vocals and piano to the song "Is This How Love's Supposed to Feel" on Ben Lee's 2007 album, Ripe.

On October 5, 2018, Martin released the second of her instrumental piano albums, titled Clear Blue Sky.
