Yin & Yang is the second studio album by Serbian recording artist Nikolija. It was released on digital platforms on 25 April 2019, through IDJTunes. The album was supported by two official singles: "Yin & Yang" and "Nije lako biti ja", featuring Serbian rapper Fox, whilst also including three standalone singles as bonus tracks: "Loš momak" (2017), "Nema limita" and "Slažem" (2018).
Nikolija announced the release of her second album in March 2019, when she also teased a collaboration with a male rapper.[6] The album's lead and title track, "Yin & Yang", was subsequently released on 29 March. It was followed by the album's second single, "Nije lako biti ja", featuring Fox, on 13 April. The music videos for other five songs from Yin & Yang were released on 24 April 2019.[7] The album itself was officially released on streaming services the following day. On 7 May, the album was also made available on compact disc in a limited series of 700 copies. The physical edition also includes previously released singles: "Loš momak" (2017), "Nema limita" and "Slažem" (2018), as bonus tracks.
In an interview with Prva TV, Nikolija stated that the album was initially supposed to be a concept record, but eventually ended as "experimental" with tracks in different hip hop-oriented genres, which she correlated to the philosophy of yin and yang.[8]
All the songs to a certain extent describe me, my personality, carry my energy and, not to be pretentious, but describe a music direction called "Nikolija"
Following the album's official promotional performance at the Feestyler nightclub in Belgrade on 9 May, Nikolija also performed the songs from Yin & Yang at the Ulaz festival in May.[10][11][12]
