For nearly twelve years, they have remained one of the most popular rock bands in Russia and the former Soviet Union.

The band was formed when lead singer Aleksandr Vasilev, while working in at a theatrical institute, was introduced to keyboardist Nikolai Rostovskiy. The two formed a band, and risking Vasilev's job, began recording their first album in one of the institute's studios at night.
