Petter Wallenberg says that as an artiste, he's passionate about making art that drives change. What he doesn't reveal is that as an activist, he also has an affinity to probe what's dangerous.

Advocating the cause of the LGBT community — of which, he is a part — the Swedish musician includes in his album, Rainbow Riots, "queer voices" from Uganda, Malawi, Jamaica and South Africa. "These are among the world's most dangerous countries for LGBT people. After the release, I was touched to receive messages from LGBT people who live in hardship," he says.
