In 1990, Grazhdanskaya Oborona broke up after playing their final concert in Tallinn: Letov stated he was afraid they would turn into a "commercial pseudo-counterculture project" and decided to put the band on hiatus. After that he started the psychedelic rock project Egor i Opizdenevshie with Kuzya and Igor Zhevtun. They recorded and released two albums, Прыг-Скок (Pryg-Skok, Hop-Hop) and Сто лет одиночества (Sto Let Odinochestva, One Hundred Years of Solitude) (an outtakes compilation, Психоделия Tomorrow, was released in 2001). In 1990, Letov ranked Русское поле экспериментов and Прыг-Скок as his best works.
