If you are in the know, the Serebro group no longer exists. Almost each of the former soloists is engaged in solo work. Also Katya Kishchuk. You can follow her life and work on your personal Instagram page (link: instagram.com/kkkkkkkkkkkkkkkkkkkkkkk___kkkk/). And also in the Apple Music musician card in which solo songs already exist under the pseudonym KATERINA: music.apple.com/us/artist/katerina/1459103220
