Petr Lesko, known as Spark7, was interested in music since his childhood. He had always been impressed by the sound of piano. He started learning how to play piano at the age of 13, but he improved very quickly because he already knew most of the basics for playing on a piano as an instrument. With time, Petr started listening more often to electronic music. Getting closer to the sound of the club music he discovered several radio shows that were mainly for Trance and Progressive. As Trance became his favorite genre as music, it also influenced him for his own sound.
