Milo De Nack was born in Wroclaw, Poland as Milosz Niziol. At the age of 16 he had to leave his homeland and move to the UK.
He joined his first band, Gelgothen, in 2010 and left in late 2011 due to another relocation, this time within the UK.
His tenure in his second band, Rager (thrash/speed), lasted longer; from 2011 until the band split up in September 2012. By the time of their demise, they had released the EP Image of Fear and played live across England.
In 2013 he opted for a change in musical direction, wanting to play rock 'n' roll and became a member of Medusa in June of that year.
