Basslinengineer is Shravan from Chennai. 

In 2008, he stumbled upon Goa on a wild biking ride from Chennai,where he explored the deep energetic frequencies of Techno/Electronic. Since then he has started taking an inclination towards the post-modern music scene and completed his Audio Engineering/Music Production in SAE New Zealand and the year after he decided to DJ and start making music to explore the cybernetic and futuristic sounds of 'psytech'. His main viewpoint is " You are your own help and support".

With strong basslines, sharp percussions and audio destructions, he is a postmodern experience always oriented to the dancefloor . Playing powerful tracks keeping his cybernetic edge he provides a psychedelic soundscape methodically designed for blowing his listener's minds.
