Marcia's childhood dream starting at age four, was to be a singer, and by age seven she also discovered the joy of writing poetry. As a teen, she sang in musical youth theatre, school ensemble choir, and after years of piano lessons, Marcia composed her first classical piece. In 1999, Marcia took a small pop song-writing class led by Jonathan Cain of the world famous band Journey, which profoundly changed the direction of her life. The next 5 years Juell applied what she had learned by performing her new singer/songwriter style piano ballads in performances around the San Francisco area. Marcia's dream became a reality in 2005, when her very first dance single Free (promo'd under the guise Angelface), shot quickly to Number 6 in the UK's Music Week Commercial Pop Club Chart. The same year, while visiting England to meet with record labels and producers, Marcia recorded Beautiful Day with DJ Matt Darey, which when released in 2007, became a smash Billboard dance hit. Marcia's original dance singles are now globally supported by dance radio and play in clubs world-wide by renowned DJ's including Tiesto, Armin Van Buuren and Markus Schulz, to name just a few.

Calling (Black Hole Recordings), CyberSutra & Marcia Juell - Fly Away (Kult Records), Bartlett Bros feat. Marcia Juell - Let It Flow (Lunatique) and Tartarus & Save My Heart (Soviet Recordings) are a few of Juell's popular single releases, all of which can be found on iTunes and Beatport. Marcia's original material has been featured in the motion picture Loaded (2008) and can also be heard playing in venues such as Nine West Shoe's and 24 Hour Fitness gyms. Additionally, Marcia was fortunate to have several song placements in the 2010 Paramount DVD re-release of Beverly Hills 90210 and Melrose Place.

Some of Marcia's collaborators include: Santana's Myron Dove, Tower of Power's Jeff Tamelier, Matt Darey, Digital Dog, Lange, DJ Peter Presta, Scott Binder (aka Banger Bros & CyberSutra), Saint (producer of Free), Andy Galea (aka Sol Brothers, Nightstylers) and Alex Bartlett (Fabio XB).
