Behind the music of Tegma are Omar Chelly and Jason Orfanidis, both born and raised in the Swedish town of Malmoe. In 1998, they started their first common project, Epsilon, which focused on melodic trance. Two years later, however, they completely fell in love with the new wave of progressive and minimal psytrance, leading to the birth of the brand new act called Tegma. Since then, they have released about 40 tracks on CD compilations and vinyls of various labels
