Relatively unconcerned by ambitions, Zoc is still an outstanding project, very explicitly showing the band members as the experienced, versatile, and talented musicians they are. The band's initiators were Blaž Celarec on drums, percussion, and clarinet and Žiga Golob on bass and ukulele. Blaž, also a member of Brina, Fake Orchestra, and some other bands, is otherwise a music composer, producer, and very much wanted musician for all kinds of projects. The same goes for Žiga Golob, the owner of one of the most extensive discographies among the younger Slovene jazz musicians.
With time, they were joined by Andraž Mazi, who plays guitar, pedal steel, and dobro, and Adi Jakša on guitar, melodica, and banjo, both active protagonists of the jazz scene and collaborators in many noticeable projects. Chris Eckman, member of The Walkabouts, sometimes also joins in.
