【Anchorwoman A XXX Parody】

A little known song called "Quiet" has made a loud statement following a passionate a capella performance at the Women's March in Washington.

In the midst of the millions marching on Anchorwoman A XXX ParodySaturday, a small collection of singers delivered a moving rendition of the song by LA singer MILCK. Its themes of strength and speaking up, and the riveting performance in a clip on Facebook, have drawn quite an audience online.

A flash mob organized by MILCK and dressed largely in pink "pussyhats" sang the spirited rallying cry of a song during the event, bringing together a capella singers from all over the U.S., NPR reports.

A short clip of the performance was captured by Israeli director Alma Har'el and posted to Facebook, gaining more than 13 million views by Tuesday afternoon.

The song's catchy, defiant chorus -- "I can’t keep quiet, no oh oh oh oh oh oh" -- seemed to resonate with many of the millions who marched after Trump's inauguration, as did its strong message of empowerment.

Put on your face

Know your place

Shut up and smile

Don’t spread your legs

I could do that

But no one knows me

No one ever will

If I don’t say something

If I just lie stillWould I be that monster

Scare them all away

If I let them hear what I have to say

Along with the song, the #ICantKeepQuiet hashtag was launched by MILCK, who tweeted messages with the hashtag in the days leading up to the march.

After the video went viral, the song seemed to evolve into a full-blown anthem -- one MILCK has said is meant to inspire and unite in the midst of oppression.

"With this song, I feel like I’m finally allowing my truest inner self to be expressed," she told Indie Mindedjust days before the march. "In this time of fear, propaganda and discrimination, it is critical for our individual and collective voices to be heard."

"With this song I’m saying I am NOT the woman who is going to stay quiet where there are figures who promote oppression," she added. "I want to encourage others to give a voice to whatever they may have silenced, political or personal."

She said she produced a music video with Director Sammi Cohen in the days following the election, as she grappled with finding the right material to bring it to life.

"I wanted the video to be raw and pure, focused on the emotions that spur from being silenced," she said. "I know that many people, beyond just women, know that feeling of suffocation that comes with oppression.”

Since the song first made waves, the #ICantStayQuiet hashtag has become a hub for people speaking out on a variety of concerns, from dealing with women's rights to the other social issues in Trump's America.
