Petter is also the founding director of Rainbow Riots, an award-winning non-profit organisation that uses arts and culture to advocate for human rights for LGBT people globally.
In 2017 Wallenberg composed and produced ‘Rainbow Riots’ - a music album featuring queer voices from some of the most dangerous countries in the world for LGBTQ people.
UK magazine Dazed called it ”the zenith of international queer activism” and British broadcaster BBC deemed it ”the ultimate protest” and concluded: ”This is advocacy”.
Remarkably Rainbow Riots was also featured in a news story from the Jamaican Observer, famously one of the world's most hostile countries towards LGBT people.
[2][3][4][5] In 2022 he composed and produced the single “We Don't Care" featuring queer voices from four different continents, including countries where it is illegal to be LGBT, all on the same song.
In 2016 during the making of the music album ‘Rainbow Riots’, Wallenberg and his Ugandan collaborators were held hostage in the police raid of Uganda Pride.
[8][9] As the creative director of Rainbow Riots, Petter collaborates with fellow LGBT artists around the world, and has created a string of high-profile international projects, several of which have become milestones in the fight for equality.
