Hollywood Undead is an American band from playing rap-rock. The band doesn’t have a long history; it was formed in the middle of 2005 in Los Angeles, California. Three years later they issued their first album Swan Songs. By now, they have released five successful albums sold in more than 10 million copies all over the world. All of the group members have their stage names, some of which are connected to their real names and some just reflect their likings and dislikes or simply the sense of humour. During their performances or photo sessions, the musicians wear masks, strictly personified and all based on the design of a mere hockey goaltender’s mask.
