Born in Stuttgart, Germany and raised in the suburbs of Chicago, Marcya Daneille has created a niche for herself as a cross-genre vocalist, vocal coach and band leader with an inspiring, eclectic musical sensibility. Marcya's earliest professional opportunities as vocalist were presented while she was still in high school and she continued to sing professionally in the Chicago-land area as she completed her degree at the Chicago College of Music at Roosevelt University (currently known as the Chicago College of Performing Arts).

Marcya resided in New York/ New Jersey for more than a decade. During this time, she recorded and co-produced her CD "Keeping it Simple" with internationally acclaimed trombonist Wycliffe Gordon. "Keeping it Simple" was recorded at the legendary Nola Recording Studios in New York, NY by engineer/owner Jim Czak. The project, which includes a blues written by Marcya and Wycliffe ("Nosey Folks Blues"), was released on Gordon's former indie label Bluesback Records and features appearances by pianist Aaron Diehl (Wynton Marsalis) and bassist Dezron Douglas (Cyrus Chestnut).

As a supporting vocalist, Marcya has been blessed to be on stage with notable artists such as Laurel Masse, Wycliffe Gordon, Sachal Vasandani, Simon Estes, Vanessa Williams, BeBe Winans and Gerald Levert. Marcya has performed at New York venues such as the Apollo Theater, Alice Tully Hall, Jazz at Lincoln Center, Ashford and Simpson's Sugar Bar, SOB's, Miller Theater at Columbia University, Crash Mansion and 5C Cafe. Midwestern appearances as a band leader include Freedom Hall, the Main Street Music Festival, Summer Sizzle Jazz Festival in Milwaukee, the University Golf Club, Chant, Red Kiva, the Art Institute of Chicago, Charles Heath Presents: Jazzin' on the South Side, Hidden Manna Cafe and Bar, the Racine Theater, Blu in the Pfister Hotel, the Jazz Estate and Carleton College. An experienced session singer, Marcya has been featured on international House music releases with DJ Stan Courtois (France) and DJ Blacksoul (Croatia), both of which spawned numerous re-mixes.
