Tromo Aka Yiannis S. was born in Athens.
His first contact with music production was during his young age studying guitar and synthesizer. After many attempts with rock and metal bands he realized that something else is his faith. Around 1997 he discovered the magic in electronic sounds and the Psytrance rhythms after going to parties and festivals around Greece and Europe.
Having the experience and influence from the dark scene, he created Tromo and had his first release in Mighty Quinn records at 2008. In nowadays, he collaborates with Drury Nevil as Ohminside and with Antonymous as Quadraphonic.
