Oliver Mazurtšak, known professionally as OLLIE, is an independent Alternative Rock artist, songwriter and record producer based in Tallinn, Estonia. OLLIE is most known for his 2022 debut rock release "Venom", which took 2nd place in the Eurovision 2023 pre-selection of Estonia. 
 OLLIE uses sound as a means to capture and amplify a certain emotion, moment or attitude. He describes his relationship with music as, "I believe that the most special things a person does comes from their intuition, and everybody has an intuition. Everything I do, when I perform or create is very natural to me. Even as a kid, I would just sit there and play the guitar until my fingers fell off. Nowadays I can't imagine my life without music. I don't know anything else." 
 OLLIEs recent explorations combine his signature electronic sound with his love for 2000s Alternative Rock, Post-Grunge, Nu-Metal and HipHop music. He also credits Rock bands System Of A Down, Linkin Park, Eminem and guitar virtuoso Steve Vai as a big role in expanding his creative horizons during his teenage years. The influence is clear in OLLIEs full and powerful sounding productions.
