In December, New Zealand musician and singer Lorde canceled a concert in Israel after two individuals from New Zealand - one Jewish and one Palestinian - co-wrote a letter calling for the singer to do so.

The 21-year-old singer's decision received backlash online, but it wasn't all negative news. Over 100 artists took a stand in solidarity with Lorde's decision in an open letter published in The Guardian

The artists - from different countries around the world - signed a pledge in support of the singer's decision, saying she has every "right to take a stand" against Israel.

The open letter came after some media outlets referred to her as an anti-Semite. The Washington Post published an advertisement in their newspaper saying Lorde is "ignoring Syria to attack Israel."

"We deplore the bullying tactics being used to defend injustice against Palestinians and to suppress an artist’s freedom of conscience. We support Lorde’s right to take a stand," the letter reads.

The artists include Roger Waters, Mark Ruffalo, David Gray and many others

Artists from around the world stood in solidarity with the 21-year-old including actresses, singers, filmmakers, painters, to name a few. 

Roger Waters - who has long been vocally opposed to Israeli aggression - is among those on the list. 

Waters has consistently expressed his solidarity with the Palestinian people.

"After visiting Israel in 2005 and the West Bank the following year, I was deeply moved and concerned by what I saw, and determined to add my voice to those searching for an equitable and lawful solution to the problem," Waters wrote in an op-ed for Salon in 2014.

He also expressed his full support of the Boycott, Divestment, and Sanctions (BDS) movement: 

"I have determined that the BDS approach is one I can fully support."
