Do Disturb

Jung began crafting the record in March 2017.[1] In midst of a break while on tour, Jung hung a "do not disturb" door hanger in front of his hotel room, inspiring the title of the record.[2][3]

Recording and mixing for Do Disturb took place in Seoul at the FNC Entertainment Studio; it was mastered at 821 Sound Mastering.[4]

A pop album,[5] Do Disturb compromises various genres in the record, distinguishing itself from Jung's previous work with CNBLUE and his solo work.[1][6] The first half of the mini-album consists of dance music, with the second half containing "slow-paced emotional" songs.[5] "That Girl" is a dance-pop song with a "funky sound".[7] "Closer" is a light medium tempo song.[6] In the lyrics, the narrator "asks his love to stick by his side". Jung described it as the "sweet" song on the record; the chorus was initially written in English, but was later translated to Korean.[2] "Password" is an "addictive" deep house track.[6] His first attempt at the genre, he described as a "party" song with elements of pop music which fixates around "repetitive" hooks and lyrics.[2]

"Navigation" is a "calm" melody which consists of piano and strings.[5][6] Set in medium-tempo, the song opens with the sound of ocean waves. It is a "lyrical" song which was inspired by his "poor sense of direction". The lyrics hint as "social isolation", but also intends to "cheer up the listener". He noted that "dreams and goals" help him "navigate" his life, and feels "lost" without them.[2] "Not Anymore" is a R&B-pop ballad which serves homage to the sound and lyricism of the 1990s by following the melodic progression and the implementation of a synthesizer common during that time period.[2][5] Jung co-wrote the song with a keyboardist, which whom he worked with on his first solo concert tour; Jeon Geun-hwa provides vocals for the chorus. It deals with the mourning of a breakup.[2] The closing track "Lost in Time" is a "traditional" ballad with a "tranquil" melody.[5][6] Jung utilized a similar chord progression to "Last Leaf" from his debut studio album One Fine Day (2015), calling it an "extension" of the song. It "captures the sadness" of the narrator seeking to forget his former lover.[2]

Do Disturb was released in two editions. The standard version cover of the mini-album depicts Jung in black-and-white monochrome, contrasted against colorful tropical plants in the form of decalcomania in order to emit a summery aura.[8] Not part of the original design, the decalcomania was inspired by a trip Jung took to Hawaii, where he "fell in love with the place". Shot in the Hongdae, Seoul, Jung collaborated with a photographer of Arena Korea magazine for the album photography.[2] It showcases him wearing a colored, patterned Hawaiian shirt.[2][9] Formed in the shape of a book, its contents include a 96-page photo booklet, a poster, and one random selfie photo card.[2][10]

Designed and hand-drawn by Jung, the special version cover depicts a red door hanger affixed with a pupil, signifying that "the eye is watching". It is set against a golden backdrop of the logo of his "JYH" initials.[2][11] The album photography shows Jung donning white apparel as sun rays shimmer through curtains, producing a "relaxed" environment.[12] He sought to take photos of "close-up shots of my body parts".[2] The packaging includes 24-page photo booklet, a poster, and one random selfie photo card.[10]

The release of the record was first announced on June 19, 2017.[1] Beginning on July 10, FNC Entertainment released a series of teasers to promote Do Disturb. The record company launched a teaser site entitled Summer Night Beginning.[8] On the following day, a concept trailer for the lead the song was unveiled.[7] A series of photo teasers were uploaded for the standard and special versions between July 12–13, respectively.[9][12] A highlight medley for the record and art spoiler were released on the subsequent day.[13][14] On July 17, a music video trailer for "That Girl" was released.[6] Do Disturb and the music video for "That Girl" featuring Loco was concurrently released on July 19.[3]

In addition to the lead single, he also performed "Lost in Time" on Mnet's M Countdown, Korean Broadcasting System's (KBS) Music Bank, Munhwa Broadcasting Corporation's (MBC) Show! Music Core, Seoul Broadcasting System's (SBS) Inkigayo, and MBC Music's Show Champion.[15][16][17][18][19]

Writing for online magazine IZM, Jung Min-jae rated Do Disturb three and a half stars out of five, describing Jung's "musical caliber" is "highly commendable". He complimented the "well-made tracks" and the "delightfully diverse genres" included on the record. He mused, "it is clear that he has solidified his competitiveness as a soloist through making this superb pop album". However, he criticized the song lyrics for its shortcomings, pointing out that the "shallow stories don't imbue much depth into one's listening, and one-dimensional metaphors don't amount to repeated enjoyment." Overall, he deemed Do Disturb as satisfying mini-album.[5]

Do Disturb earned Jung a nomination for the Golden Disc Album Award at the 32nd Golden Disc Awards.[26]
