Following the success of ‘Princesses Nubiennes,’ Les Nubians toured extensively and collaborated with a number of U.S. artists, including Black Eyed Peas, Reflection Eternal, and Jimmy Summers. “We did a lot of [other] music and touring between albums,” Helene Faussart tells Billboard.com. “After we wrapped the tour, we had a lot of ideas. We felt fresh and full of inspiration. We evolved as musicians, women, mothers, and humans.” Sisters Helene and Celia Faussart return with ‘One Step Forward,’ their sophomore set for OmTown/Higher Octave (March 25).
