With Lizorkina at the time, the band recorded their debut studio album "OpiumRoz". The album received critical acclaim and spawned other singles in addition to "Song #1", but it never became a commercial success. The band's second album, called "Mama Lover", proved to be much more successful. It included the massive hit of the same name and went double platinum in Russia. The eponymous "Mama Lover" hit single received media attention worldwide, with reviewers commenting on both the raunchy music video and the song itself. The music video for the song received more than 20 million views on YouTube and became the subject of more than 250 parodies. After the success of "Mama Lover", the group began to garner commercial attention around the world. The group re-released "Mama Lover" in Japan (under the name "Serebration") after signing a contract with EMI Music. Their first international single under Ego Music and Universal Music Group, "Mi Mi Mi", became a success on European music charts.
