[4] To promote their debut album, Serebro organised an outdoor concert on April 25, 2009, at Poklonnaya Hill, Moscow where fans were free to attend.

Band member Elena Temnikova said of the concert: "We do not want to organize a feast during the plague, to make the grand presentation with champagne and caviar, as it is in our show business.

In a difficult economic situation in Russia and in the world to arrange a costly celebration on the occasion of the release is not right.

We spoke to people who supported us over the past two years, who were anxious for us, listening to our songs, have been and remain our loyal fans.

"[5] Other acts were asked to perform alongside Serebro and the line-up included Band'Eros, Mitya Fomin, Total and two new Maxim Fadeev projects, Voron and China.

The fourth single to be released from the album, "Скажи, не молчи", was later re-recorded to include the vocals of new group member Anastasia Karpova, Marina Lizorkina's replacement.

The review said that "Sound Sleep" saying "the five-minute psychedelic art-rock with magical sketch whisperings and scope of ethnic ostinato riffs that sends almost to Pink Floyd.

All the group's releases, including Mama Lover and EP's remained on the iTunes accounts and this now means that OpiumRoz could be counted as a collectors item physically and digitally.

The album's songs, including non-singles like "Angel Dust", "We Take Off" and "Under Pressure", can still be searched on live streaming music websites.
