Exit: E

The majority of the album was produced by the members themselves, much like in their full-length album 2014 S/S, though with limited contribution from leader Seungyoon. Member Taehyun was the main composer for both title tracks, "Baby Baby" and "Sentimental". Kang Uk-jin was a frequent presence in the album as well, who had previously helped Big Bang member Daesung with his second Japanese album D'slove. Frequent Sistar contributor lyricist and producer Rovin, assisted Taehyun with his solo single "I'm Young".

During the 18-month long hiatus, the members took the time to study more about music producing and songwriting in order to expand the variety in their sound. Jumping straight from the CJ E&M produced "Show Me The Money" rapping survival show, Min-ho expressed relief in being able to leave the 'intense' atmosphere behind..."[hiphop itself] is a scary type of music and it’s not like there is a rule that you need to do everything with strength but the program 'Show Me The Money' itself is an audition program where they make all the rappers compete with each other so it can’t be helped that there is a atmosphere that pressurizes the mentality." Going on to explain that the hiphop scene was somewhat restricting, he revealed that the members were more comfortable working together on Exit: E than on their previous album, where they had encountered disagreements stemming from different musical styles. Taehyun, meanwhile, listened to B. B. King, blues rock, and modern rock in order to expand his musical experience, and incorporated those styles in the songs he contributed to the album. He learned to play the guitar during the break as well.^[2]

The physical album was released the following day and came in two versions: "Alexandra Palace" and "Shoreditch". A limited physical edition, called "Westminster", was released on March 12, 2016.

The album features five tracks, including the double title songs "Baby Baby" and “Sentimental”, Mino and Taehyun's duet “Pricked”; as well as a solo song "I'm Young" by Taehyun.^[3] "Baby Baby" was described to be a blues-infused song, and "Sentimental" a rhythmic minor pop track “Sentimental”.^[4]
