Mukka (Serafim Sidorin) is a Russian rock musician. Born on July 26, 1994, in Nizhny Novgorod Oblast.

In an interview on the YouTube channel "Chay vtroem", he declared that "Crimea is ours."
Listening to this artist's tracks on official streaming platforms, social media, and other services indirectly contributes to financing the war — through taxes paid to the budget of the Russian Federation.
Mukka's stance on the war in Ukraine
On the eve of Russia's full-scale invasion of Ukraine, on February 21, 2022, Mukka published a post on Telegram, "sincerely" expressing bafflement as to why Ukrainians were so hostile towards Russians:
Explain to me who all these Ukrainians are (or is this some kind of organization I don't know about, or what could it be) who in the comments call us (ordinary, f**king people living in Russia) «rusnya,» «moksapidars,» «sovok-whores,» and so on? I genuinely don't get it, do Ukrainians really think of us like that? Do they think we need something from them over there? The ordinary, f**king people? Vasya from the Gorky Automobile Plant? I don't get what we did? Or are these just like radicals? Help me understand. Especially interested in the opinion of guys from Ukraine
On February 24, 2022, while "hungover," Serafim posted numerous stories deliberating whether to release his new song "Voyna" (War) when "such f**king bullshit is happening." He then supplemented this series of "highly intellectual" reflections with the phrase:
The thing is, I didn't say that anyone over there was right or wrong. I didn't support anyone's side. I simply said that war is complete f**king bullshit...
Serafim also wrote that Ivan Dorn had "disgraced himself," posting a screenshot detailing the "termination of Dorn's cooperation with Russian artists, partners, and record labels."
Discussing alleged fakes, Mukka, who had served three years in the Russian army, insisted that Russian soldiers always look "spick-and-span," all clean-shaven and neat, while showing "unshaven, pot-bellied, overgrown semi-alcoholics is definitely pure bullshit."
In June 2023, following "showdowns" with Ekaterina Mizulina, head of the Safe Internet League, he stated that "I don't write new [songs] about drugs," and old tracks referencing narcotics were censored ("blurred") across all streaming platforms.
"Infected with patriotism and imperialism," in 2024 the artist rolled out posts reading "Glory to Russia" and "Russian Empire":

The artist lives and works in Russia, actively touring across Russian cities.
