There are at least two artists called Zef. 1) Zef is a Chipmusic Project which seeks to put the Gameboy hardware to its limits, transcending genres and traditional styles Zef rocks out in 8 bits of hardcore electro. 2) Zef - Undoubtedly one of the best live folk bands on the European circuit at the moment. These extremely talented young french musicians put not only great technical skill, energy and enthusiasm into their performances but also play with immense feeling and emotion - a rare gift in a group so relatively young !
