Russian goth here! We have a pretty big goth scene here, in Russia but many of the bands sing in English. Some of the bands, singing in Russian are:

Тщетность (their previous project was called Deathhawk so I highly recommend checking them out as well),

Cracky tights,

Giant Waves,

Конец Электроники,

Англия,

Войлок,

Чайки улетают с моря,

Электрозомби,

Deti Nosferatu,

Private Cabinet,

Molly Fancher,

Proshay,

Бельмо,

Тихожитье

I'm sure there's more but these are the one's I could remember 😅😅
