Katy Perry, Cardi B, and Justin Bieber have pledged to try and hire more female producers as part of the Recording Academy’s new diversity push.

Katy, Cardi, and Justin are joined by a host of star names, including Lady Gaga, John Legend, Shawn Mendes, Nicki Minaj, Pink, Post Malone, Carrie Underwood, Keith Urban, in committing to considering at least two women when hiring producers or sound engineers.

The new initiative from the Academy, who organizes the annual Grammy Awards ceremony, is aimed at increasing the number of female production staff from minuscule levels.

According to a 2018 study, only two percent of music producers and three percent of sound engineers or mixers in pop music are women.

Rapper Common, who is helping spearhead the initiative as a member of the Academy’s Task Force on Diversity and Inclusion, also said he is “proud” to sign up to the pledge.

The Task Force was established last year following an outcry when only one major Grammy Award, the Best New Artist prize bagged by Alessia Cara, went to a woman.

At this month’s 61st Grammys ceremony five of the eight acts nominated for the prestigious Album of the Year category are women, with Cardi, Brandi Carlile, H.E.R., Janelle Monae, and Kacey Musgraves all receiving nods.

Female artists also well represented in the Best New Artist, Record of the Year, and Song of the Year sections.
