Love the lead in the intro. Makes a strong statement to start the music rockin'...very important after that catfish monster thingy !!!
I think the bass, being brought out more in the mix, would enhance the earthy feel of the song. I know, everyone has called it sci-fi...but I pick up a crazy mix of 'earthy sci-fi' aura from it. The words are out there and the bubble effect takes it on a trip, but the bass, drums and rhythm guitar brings it back to earth and grounds it in some heavy sounds. I love the mixture.
The snare could come up with a more defined pop in volume and the kick a bit more thud...? I can hear some great tom rolls in there throughout the tune, to break the repetitiveness up too.
Have you considered using the bubble effect on the outro as well, to give it a tripping away effect? It seems natural for the journey to end tripping out, as it had started tripping in....Just a thought...
...after reading this, perhaps I am the one tripping!!
As usual....kick ass stuff axeman!!!
