2AM had an open rehearsal for their upcoming concert and expressed their thoughts about coming back with their 3rd mini album. Their general thought is that they do not stress about the need to change.

2AM is busy these days as they near the release of their album and their concert, both named "NOCTURNE". During the open rehearsal, they were asked about whether their music is any different. They responded by saying, "We used to stress out about the need to change our repertoire or style, but we realized that there really is no need to change ourselves to give an illusion of our evolution as musicians."

Seulong stated, "We are comfortable doing our music, so the only thing that we felt was necessary on our end was to try to challenge different songs with our style. That's why we collected songs from different composers for this mini album. That way, we are not pressed to be a group or a style that we know we are not, but at the same time, we can bring different genres of music to our fans '2AM' style."

On the concert to be held in December, they said, "Fans of 2AM may think that our concert format is always the same. We don't want to bore our fans so we're looking into doing some collaborations with other artists and bringing in different genres."

2AM is releasing their single "Just Stay" as a pre-release and will follow it up with the release of their mini-album "NOCTURNE". They showcased the song on the open rehearsal. They also showcased an all-acoustic version of "Can't Let You Go Even If I Die". Their title song for the upcoming album, "Regrets", was also song in front of an audience.

2AM will have their concert on December 7th and 8th. They will follow it up with a concert in Los Angeles on the 15th and Taipei on the 21st.

Their new album is releasing on the 27th.
