Vortex (5) is a French duo consisting of Nicolas Guerrero (vocals, guitars, electronics) and Sonia Cohen-Skalli (bass, vocals, tapes), who started working together some years ago, and were influenced by groups such as Suicide and My Bloody Valentine, as well as the noise/industrial scene. As time passed they opened their ears to contemporary music (Ligeti, Arvo Part, etc..) and rehearsed almost a year before producing their first album. Eksaiphnes is a very electric album, with walls of guitar sounds, vocals deep in the mix, but also featuring quiet instrumental pieces of music in more of a ambient mood.
