Sektor Gaza (Russian: Сектор Газа, translated Gas Sector) was a Russian rock band formed on 5 December 1987 in the city of Voronezh, Russia. Despite only semi-officially existing (due to obscene lyrics), the group remains popular in Russia today. The group name was taken from an eponymous industrial district of Voronezh (itself named for high levels of environmental contamination). Their music style could be defined as Russian punk, integrated with elements of different musical genres such as rock, rap, and Russian folk.

A punk-opera named "Kaschey-the-immortal" was released in 1994. It is a punk version of a famous Russian fairy tale with the name of the evil protagonist taken as its title. In this album Yuri has borrowed musical themes from a number popular groups such as AC/DC, Queen, Ace of Base, Nirvana, infusing them with his own lyrics. The album ranked in the top 10, and journalists called "SG" "a young promising group from the back of beyond".
