The themes of her music include social and political turmoil in Lebanon (Saleh was six years old when the Lebanese civil war began).
Her childhood and teenage years were affected by her parents' divorce, the civil war, and the fact that her mother was raising her two daughters alone.
She experimented with image and sound, created illustrations, animations, video art, and wrote music jingles for Future Television.
Saleh wrote the lyrics to Natacha Atlas' song "Communicate", released on Lebanese band Blend's album Act One.
Saleh wrote the lyrics for and coached the singers in Khaled Mouzannar's soundtrack for Nadine Labaki's second feature film Where Do We Go Now?
She also shared the stage as a guest with Lebanese trumpet player and composer Ibrahim Maalouf at the Byblos International Festival the same year.
Her musical collaborations are eclectic, including: Ziad Rahbany, Toufic Farroukh, Issam Hajali, Charbel Rouhana, Ibrahim Maalouf, Rayess Bek, Khaled Mouzannar, RZA, Nile Rodgers, Charlotte Caffey, Tarek El Nasser, Natasha Atlas, Bernd Kurtzke, Erik Hillestad, Anneli Drecker, Mathias Eick, Kjetil Bjerkestrand, Terry Evans, Hazem Shahine, Lisa Nordström, Bugge Wesseltoft, Kari Bremnes, Øyvind Kristiansen, Lina Nyberg, and Chinese Man Records.
