2gether is the second studio album by South Korean pop rock idol band CNBLUE. It was released on September 14, 2015, under FNC Entertainment. After ending domestic promotions for Can't Stop (2014), the band concentrated on individual activities; most notably, frontman Jung Yong-hwa released his debut solo album One Fine Day (2015) in January. The remaining band members sought out opportunities in television, particularly in acting, variety show appearances, and MCing. In August 2015, it was announced that CNBLUE would release its second studio album after an absence lasting one year and seven months. With 2gether, the band decided to change the direction of its music; it stripped itself of the acoustic tracks it was known for and explored electronic dance music in order to create a particular color and form a distinctive sound.

After a series of photo and video teasers, the album and lead single "Cinderella" were released simultaneously. The band held a "Be My Cinderella" album showcase on the day of release and began promoting the album through music chart programs across various television networks by performing "Cinderella" and other album tracks. The single ultimately led the band to win a total of five music show trophies: two consecutive wins on both SBS MTV's The Show and Korean Broadcasting System's (KBS) Music Bank, and one on MBC Music's Show Champion. 2gether was met with generally favorable reviews, particularly for the band's pursuit of electronic elements. The album went on to top the Gaon Album Chart in its second week of its release and sold 83,000 copies in its home country. The band embarked on the 2015 CNBLUE Live "Come Together" concert tour, which made stops in South Korea, China, and other countries in Asia.

Background After ending domestic promotions for its fifth mini-album Can't Stop (2014), CNBLUE pursued individual activities. Frontman Jung Yong-hwa released his debut solo studio album One Fine Day (2015) in January and embarked on an Asian tour. Guitarist Lee Jong-hyun played the role of a lead character in KBS2's Orange Marmalade and participated on MBC's reality variety program We Got Married. Drummer Kang Min-hyuk took part in MBC's I Live Alone and KBS2's sports variety show Our Neighborhood Arts and Physical Education. Bassist Lee Jung-shin was an MC for SBS Plus's Fashion King: Secret Box and Mnet's music chart show M Countdown.

During a press conference in June for the 2015 Jung Yong-hwa Live "One Fine Day" concert in Taipei, he disclosed that, upon the completion of his solo promotions, CNBLUE was set to release an album in the second half of the year. On August 24, 2015, it was announced that the band would release its second studio album in September. Four days later, it was revealed that the album was titled 2gether and had a set release date of September 14, one year and seven months following Can't Stop.

Writing and development CNBLUE began developing songs for 2gether in midst of writing songs for Can't Stop. While staying at a hotel in Japan during the band's Arena Tour 2013: One More Time, bassist Lee sought out to write a song. Jung assigned him and Kang to do it together; after listening to the melody of "Control", the two conceived the idea of writing a love song, which Jung rejected. After discussing it between themselves, Kang and Lee agreed to write a song with the notion that "no one can control me". Initially written in Korean, the two faced difficulties in translating the song into English. With the assistance of Jung, the translations and lyrics were completed; Kang and Lee were left uncredited. The song was originally intended to be included on Can't Stop, but was ultimately excluded. Jung cited the limited space on the release, as well as the "different atmosphere" the song had in comparison to the other songs for its omission. He decided to add it to the band's Japanese single "Go Your Way". The lyrics were rewritten in Korean by the bassist for its inclusion on 2gether, marking the first song to be credited under his name since the debut of the band. "Radio" was previously recorded in Japanese for CNBLUE's album Wave, which was re-recorded in Korean for inclusion on 2gether. "Footsteps", originally titled "Heart Song" and included in its Japanese single "Truth", was also rewritten in Korean. In midst of filming KBS2's Orange Marmalade, guitarist Lee took the opportunity to write "Hero".

Often compared to American pop-rock band Maroon 5, CNBLUE has found the comparisons "honorable", but has expressed its desire to distinguish its musical color and establish a unique sound. In CNBLUE's previous albums, Jung made a conscious effort to record music in order to receive recognition for it as an idol band. After deciding to disregard those notions, he opted to create "more comfortable" music that suited the band; as a result, the acoustic music which was present in the band's previous albums was entirely excluded from 2gether. In developing the record, CNBLUE set out to "really [come] together with our music, working with each other on the compositions". CNBLUE took the initiative to change the sound of its music for a "more mainstream feel" by integrating elements of electronic dance music into the album. The title of the album was conceived by Jung while he was eating patbingsu with bassist Lee. It signifies CNBLUE's second studio album, as well as enjoyment of the band's music together. The album was recorded in Seoul at the FNC Entertainment Studio. Mixing took place there, as well as at Cube Studio and MasterPiece SoundLab; it was mastered at the SUONO Mastering Studio.

Music structure Musically, 2gether explores the Top 40, electro, and alternative rock. "Cinderella", the lead single of the album, is a pop-rock song that incorporates disco and elements of electronic music. The song begins with "warped vocals, zipping synths, and booming drum machines" before building up into the "explosive chorus", leading into its catchy hook. The song was written and composed Jung and serves as a take on the European folktale of the same name with "trendy sounds" and "modern sensibilities". "Hide and Seek" is a track that affixes a blaring saxophone. "Roller Coaster" is a pop-rock song with influences of reggae and ska, melded with a synthesizer. In "Domino", Jung mixed CNBLUE's traditional rock sound with popular music to appeal to the masses. Consisting of "crunchy" synths coupled with a funk rhythm guitar, the 1980s synthpop song features Wheein of girl group Mamamoo, the band's first ever feature. Written and composed be guitarist Lee, "Hero" is a song reminiscent of 1990s alternative rock. He created it in tribute to his father, his first attempt to write a song for him. "Catch Me" is a rock song which draws inspirations from 1980s dance music and is blended with a synthesizer. A synthpop song, "Drunken Night" describes the emancipation from the burden of expectations with a night out of alcohol consumption. "Hold My Hand" is a medium-tempo jazz pop song infused with a "romantic" clarinet. An electronic rock song, "Radio" features a heavy guitar and a synthesizer. "Footsteps" is a Britpop-inspired song that deals with the idea of finding footprints along one's path that others have traveled, signifying "you are not alone".

Artwork concept and packaging 2gether is available in three editions. The concept of version A revolves around the theme of morning and showcases CNBLUE's "sexy change". It includes a 68-page photobook, one out of four random photo card between two sets, and a poster.
