Marx Morta is the pseudonym by which front man of The Sixth Letter Marcus goes by.

Producing bass & beats oriented music as a side project to the band, it scratches the creative itch and pushes the production possibilities within TSL itself.
 

With this project the Rocstar Recordings connection continues on after the band's sound went in a different direction.

Actively dj'ing throughout the TSL career, playing sets across europe in recent years, Marx continue to explore as many creative avenues as possible - by maintaining the one that got him started in the first place.
