Yes... i agree with all of you guys ... except for Etter. The bass sound on " A Sceptic's Universe " is monumental, phenomenal... and very much essential... it gives a more aggressive taste to the music... that's why i'd refer to Spiral Architect's music as Aggressive Progressive (LOL).... and technical ofcourse... with lots of fusion/jazz elements bla bla bla.... you get my drift guys

... and by the way, gypsyshred makes a very good point about most bassists in rock/metal bands... you can hardly hear their sound !!
