Willow Smith is following in the sneaky footsteps of Beyonce. In a surprise move, the 15-year-old singer dropped her debut album Ardipithecus on Friday.

The 15-track collection is quite the departure from her 2011 hit “Whip My Hair.”; She opened up about the album over email with music website Fader. “Ardipithecus Ramidus is the scientific name of the first hominid bones found on earth,” she wrote in an email. “I wanted to name my musical compilation after it because while I was making these songs I was in such a transitional state. Digging deep in the soil of my heart and finding bits and pieces of my ancient self that tell stories, which end up being the lyrics to the songs.”

The creative teen went on to express how excited she was to release her first full-length album to the world. “Ardipithecus is my first album in my entire career and it makes me feel so blessed to be able to share my evolution with the LightEaters as I continue excavating my inner worlds,” she continued. “These songs were created through characters I have developed within my mind.”

Ardipithecus, which features Willow as the sole songwriter on 14 out of 15 song and producer on 10 of the tracks, was released on Friday by JayZ’s Roc Nationa Label.
