Gaston Philippe Abe Abe, popularly referred to by his stage name “Valsero,” is a Cameroonian rapper, activist, and human rights defender. Born in Yaoundé, Cameroon, he spent his early years in Marseille, France before resettling back in Yaoundé. In 1990, Valsero officially launched his music career, collaborating with musician Bachirou to form the rap group Ultimatum. One of the first groups of its kind at a time when hip-hop and rap were not taken seriously in Cameroon, Ultimatum paved the way for other hip-hop artists in the country. Valsero runs a campaign of mobilization and sensitisation of the youth with his association Jeune et Fort (Young and Strong) which promotes education to citizenship, democracy and electoral culture. In 2007 he launched the campaign “Va voter” (“Go vote”) that became in 2011 “Je vote donc j’ existe” (“I vote, I am”). In 2012 and 2013 he started a struggle against AIDS with the campaign “Je l’ai fait et toi…” (“I did it and you …”) in schools. He was arrested in January 2019 near a pro-democracy demonstration. Organizers, fans, and artists around the world, including PEN America’s Artists at Risk Connection, called for his release, believing his detention to be a direct attempt to silence a prominent critic of the ruling regime. He was finally released on October 5, 2019. He has collaborated with artists such as Manu Dibango, Fally Ipuba, Alpha Blondie, Tiken Jah, and French rappers La Fouine, Soprano, Kery James.
