To promote the album launch, Katina embarked her first street concert that was held on Arbat, Moscow on the same day.

[1] Katina has collaborated with several talented musicians and authors from her homeland Russia and other Slavic countries such as Ukraine and the Commonwealth of Independent States.

[2] After the release of her debut album, Katina's vision to be a superstar in the Western market failed.

As a mother, she only managed to have few collaborations with some local artists from her country but it was on 2018 when rumors spread that Katina have already began working on her second album.

[11] When the singer was asked regarding the meaning behind the album name, "I am now mono, that is because I am alone; independent as a solo artist."

Her vocals can be hardly recognized during the course of listening, for some reason, the names of Alisa Mon and Svetlana Vladimirskaya came to my head.

"[16] A less stellar review was published by Onet Muzyka, "The album Mono is simply a collection of songs that Lena Katina shared on YouTube over the last two years.

"[17] In an interview with Teleprogramma, the singer defended, "Mono is not just a collection of tracks - it is a life philosophy that is united by one red thread."
