Miron Fyodorov, better known by his stage name Oxxxymiron or Oxxxy, was born to a physicist and a librarian in 1985 in Leningrad, USSR. Following his father's ever-changing work positions, the family moved to Germany in 1994 and then to the UK in 2000.

Oxxxy graduated from Oxford University with a B.A. in English Language and Literature, having focused on the Middle Ages. During his Oxford years he was diagnosed with manic-depressive disorder, expelled and re-admitted to the university. Before achieving success in the music industry, Oxxxy earned his living with a medley of full- and part-time jobs including those of a private tutor, warehouse worker, office clerk, translator, shop-assistant, tour guide, compere, guardian and ghostwriter. He is divorced.

Oxxxy has been making hip-hop with varying degrees of consistency since the late 90s. In 2008 he began to publish his tracks online and achieved considerable renown in the Russian-speaking hip-hop scene due to his participation in the largest Russian online rap battle. In 2011, while living in Canning Town, East London, Oxxxy released his controversial debut album "Vechnyj Jid" ("The Eternal Jew") which appealed to listeners far beyond the hip-hop scene and earned him the "Newcomer of the Year" award at the GQ Magazine "Man of the Year 2012" awards in Moscow. Since then, two mixtapes, "miXXXtape I" and "miXXXtape II: Dolgiy Put' Domoy" ("The Long Way Home") have been released, the latter being selected as one of the Top 25 Russian Releases of 2013 by the prestigious Russian music journal Afisha Volna.

Oxxxymiron has been dominating the Russian urban scene in 2015 and 2016. He broke the world record for rap battles with 1 million views on YouTube within the first 24 hours and released his second studio album Gorgorod, the most anticipated Russian urban album of 2015, which charted at #1 on iTunes Russia for 2 weeks and received a flood of reviews and publications across the media spectrum. Oxxxy was named Artist of the Year according to Russia’s main hip-hop media pages - The Flow and Novyi Rap - and won in other nominations including Album of the Year, Track of the Year, Video of the Year. His shows are sold out one month in advance.

Oxxxy has collaborated with numerous Western artists including Madchild of the legendary Canadian duo Swollen Members and the German hardcore rappers Automatikk. He is also widely regarded as the first artist to have successfully adapted and popularised UK grime music in Russia, with the famous GrimeDaily website dubbing him the "Russian grime sensation".

Since 2012 Oxxxy has been touring extensively, having teamed up with the concert agency Booking Machine which specialises in post-metal and alternative urban music including Dope D.O.D. and Dub FX. He also performed at various festivals including Picnic Afishy (Moscow, 2012, headlined by Lauryn Hill and 2016, headlined by Chemical Brothers) and Tuborg GreenFest (St. Petersburg, 2013, headlined by Limp Bizkit), as well as opening for The Prodigy (Kyiv, 2013) and Yelawolf (St. Petersburg, 2015).
