Shock of the New Era is the second EP played by South Korean boy band Beast, and was released by Cube Entertainment on March 1, 2010.

The songs were written and composed by Shin Sa-dong Tiger and Lee Sang-ho who crafted Beast's previous singles like "Bad Girl" and "Mystery".

Their title song "Shock" is being reviewed as serving a powerful voice while having a strong sound with an abundance of melting sensibility.

On February 27, the full video teaser was released, titled "Just Before Shock", which is also a shorter version of the first track on the mini-album.

The whole scene then shifts into a dark storehouse-like room with the members of Beast sporting a powerful chic black-toned concept, dancing to the song's main choreography.

Throughout the music video, the scenes changes alternatively from the group dancing together in the dark room to individual shots, either sitting on a large white lego chair or standing behind a fire.

At the end of the music video, a lady is shown sitting on the white lego chair, touching a customized headphone.

A representative from Cube Entertainment revealed that the girl is on the same age as 4Minute's Sohyun and is currently preparing for her debut at the time of filming.

The main points and concept of the choreography of this dance included the members of Beast motioning themselves like they were in front of a mirror and making expressions with their faces as stated on Haw's Cyworld.
