Utah Bremner and Jim Clay Ether Harper aka "Utah" and "Ether" are two American graffiti artists. They are considered the "Bonnie and Clyde” of the graffiti world. These writers are best known for having tagged buildings and trains in more than 35 countries on five different continents. They are members of the MUL crew, which stands for "Made U Look". While Utah and Ether’s work can be found everywhere from zines, to mailboxes, walls and vehicles, they have made a huge impact on the freight scene, frequently hitting whole cars and multi-color productions on trains all over the world.
