imo this is very injustified use of the 8 string, it may be tuned very low, but does not add heaviness or anything; i don't know :s I just can't see the use of it.
Not to mention Meshuggah is hardly musical. Innovative, rhythmically challenging, genre-defining, and influential, sure, but not 'musical.'
What is wrong with you people?
strange shit for a "musician"(?) to say...
