Zdar, whose real name was Philippe Cerboneschi, and his bandmate and Hubert Blanc-Francard AKA Boom Bass, were considered pioneers of the French dance music scene in the 90s. The duo produced and remixed many hit tracks for fellow musicians, including Phoenix, Hot Chip, Beastie Boys and Franz Ferdinand, while their own music was sampled by Jay-Z and Kanye West.
His peers expressed their sorrow and disbelief on Twitter, including Calvin Harris, David Guetta, Mark Ronson, The Black Madonna, Franz Ferdinand's Alex Kapranos, and former Vampire Weekend member Rostam.
