Время и Стекло (Vremya i Steklo)

Vremya i Steklo (Time and Glass) was a Ukrainian pop duo formed in 2010, consisting of Aleksey Zavgorodniy, known as Positiff, and Nadya Dorofeeva, known as Dodo. Dorofeeva had previously been a member of the girl group NikitA before launching this project with Zavgorodniy, and the duo quickly became one of the defining acts of Ukrainian and broader Russian-language pop in the 2010s.

Their sound combined glossy electropop and dance-pop production with playful, hook-driven Russian-language lyrics, often laced with irony and internet-era slang, which set them apart from more conventional Slavic pop acts. Songs like Kafel, Troll, Imya 505 and Na stile became club and radio staples across the former Soviet space, and their videos leaned into bright, stylized visuals that matched the music's ironic pop sensibility.

The duo announced their breakup on 11 March 2020, with their final single Last Dance released that July, closing out a decade-long run as one of the most recognizable pop projects to come out of Ukraine.
