6) Psychonaut is a three-piece post-metal/sludge band from Mechelen, Belgium. Together, they create a whole of atmospheric riffs and rhytms where feeling the music with all senses instead of only the ears is a guiding light.

As for a description of their music, one could say that they create a mix of trippy, psychedelic influences along the lines of Pink Floyd combined with the heavier influences of bands like Tool, Amenra and Sleep. The power of their songs lies in the variation between these two main anchor points and by toying with these sometimes paradoxal energies, they generate the PSYCHONAUT experience.
