“Free Me” is a new song by Sia that’s meant to raise awareness and money for possible vaccines to help break HIV and end AIDS, and today it’s been officially released alongside a music video that stars Zoe Saldana as a pregnant mother that’s just found out she has HIV and Julianne Moore as the narrator. As with most Sia videos, Saldana participates in an elaborate interpretative dance choreographed by Ryan Heffington. Watch and listen below.
