Young zydeco musicians such as C. J. Chenier (son of Clifton Chenier), Chubby Carrier, Geno Delafose, Terrance Simien, Nathan Williams and others began touring internationally during the 1980s. Beau Jocque was a monumental songwriter and innovator who infused zydeco with powerful beats and bass lines in the 90s, adding striking production and elements of funk, hip-hop and rap. Young performers like Chris Ardoin, Keith Frank, and Zydeco Force added further by tying the sound to the bass drum rhythm to accentuate or syncopate the backbeat even more. This style is sometimes called "double clutching."
