# The Clan Pt. 1 Lost

The Clan Pt. 1 Lost (also stylized as The Clan Pt. 1 'LOST') is the third extended play and the first part of The Clan series by the South Korean boy group Monsta X. It was released by Starship Entertainment and distributed by LOEN Entertainment on May 18, 2016. It consists of six tracks, including the singles "Ex Girl", "All In", and "Stuck".

## Background and release

In April 2016, the group announced that they would release The Clan series, revealing the first concept as Part 1: LOST. On May 9, the track "Ex Girl" featuring Mamamoo's Wheein was pre-released. On May 18, the title track "All In" was released, along with the EP.
The group held their comeback showcase on May 18 at Yes24 Live Hall in Seoul and was streamed live on Naver's V App.
The music video for the title track was released on the Starship's and 1theK's official YouTube channels on the same day, directed by the award-winning film director Dee Shin.
The EP was released in two versions; Found and Lost.

## Composition

The EP depicts the loss and pain of youth, containing young people who live with pain in their hearts and having tragic ending through loss.
The track "Ex Girl" is a mellow pop R&B track, describing a man's regret about the one who got away. The title track "All In" is a hip hop track that highlights the group's signature powerful sound and move; it also features a thumping beat and furious raps.

## Critical reception

Writing for Dazed, Taylor Glasby described the music video for "All In" as ambitious and provocative, "but the video almost backseats the song to a soundtrack", which Glasby also describes as "far better than the MV gives it the chance to be, particularly the crooning chorus".
