Adam Krzysztofek (born 11 August 1990), better known by his stage name Varn [vɑ:rn], is a Polish record producer and DJ. He was interested in creating music and playing instruments since he was a child. In 2009, he delved into the EDM trend. He started his career five years later by releasing a few Big Room House tracks. Initially associated with Blood Diamonds Record, he preferred to combine hard dance genres with classic instruments. Under the wings of Alveda Music and ShiftAxis Records, he produced a few songs in a slightly milder style. After several years of searching for his style, finally found himself in Hardstyle. He produced his first hardstyle track „Come See Us” which was released on the Dutch Master Works label. As a result, he was supported by DJs such as Timmy Trumpet, Will Sparks, Tony Junior… In 2024, he made his stage debut. During an event called „Freedom – Key To Infinity” he presented ten of his Hardstyle tracks.
