you asked for progressive rock samples with "close to the edge bass guitar," though I'm more into progressive metal, so I sampled the best songs of Liquid Tension Experiment. Not Victor Wooten level virtuosity, but great sounding bass nonetheless. Although in the following samples you can hear why Mike Portnoy is often considered the world's best drummer.
PROGRESSIVE METAL extreme bass boost version
- these are preamped to -24dB, so once you crank up the volume +24dB you'll hear the mid to high ranges at reference normal volume with the bass boosted, so if your reference normal volume is 100dB, the bass gets boosted to 124dB and if you don't own the JVC HA-SZ2000 you are going to cry so hard
- also recommended setting the Fiio E12 bass boost on
Liquid Tension Experiment (Universal Mind and Paradigm Shift medley):
And their best song, Acid Rain:
The "elitist" prog metal favorites are Spastic Ink and Blotted Science. In fact you can hear a tribute to Spastic Ink - Mad Data Race in Liquid Tension Experiment - Paradigm Shift. As for SI and BS, personally, as much as I am impressed by the complex time signatures (structured based on Schoenberg's compositional theory), the antimelody is not for me. I love melodic dissonance and cacophony, but only when the basis of this dissonance is part of the composition--meaning, they must create first what they destroy, and one great example of that is Chopin - Tristesse. This is kinda like reading James Joyce's Ulysses--it's the kind of book you'd love to write, but not to read (in music, the kind you want to play/compose, not to listen to). What I love about Liquid Tension Experiment is that they know how to write consonant melodies on top of being gods in their instruments (I'm talking mostly of the Dream Theater guys).
I loved those two tracks - big thanks for introducing me to the awe that is Liquid Tension Experiment - I've been checking out some of their other tracks on YT today listening with my JVC SZ1000 cans driven by Fiio E12 amp with bass boost setting turned on - these guys are seriously accomplished musicians for sure, shown perfectly in the below live in NYC gig
On a different note - I found a segment in this below documentary exploring the worlds strongest materials which covered the attributes and some current applications of carbon nanotubes, the material used to manufacturer the drivers in the SZ1000 and SZ2000 and also with many other models of headphones manufactured by JVC.
If you fast forward the below video to 26mins 35secs in from the start, a good insight to how carbon nanotubes are constructed and made up at the molecular level is shown, and just how an amazing material it is that JVC have utilised in addition to the Kelton method subwoofer system, into these two pretty special if not unique headphones
