This one is BreakbeatEra's title song from the "UltraObscene" album. It's a great album which falls in the Drum&Bass style, but has strong trip-hop and jazz influences. Good dynamic recording, although you can pickup quite a few of the mix's glitches usually blended out during mastering.
I use this album when I auditioned equipement and it often just isn't right. Maybe this is why... with a strong beat centred at 40Hz... and extension to 8Hz, A LOT of info was missing...
Ok, How about Meat Beat Manifesto's "YURI" from their "RUOK" album? This is techno-industrial with excellent recording quality throughout the whole frequency range and beyond. I would refer to this as a bass intense recording though.
Bass extends evenly to below 10Hz... a lot of info between 20Hz and 50Hz. It'll make most speakers (and a lot of subs) sweat.
This is for those who prefer "analog" instruments... Korn's "Did my Time" which many will remember from the Lara Croft Tomb Raider: The Cradle Of Life movie. Your typical metal band with guitar, drums, bass, and vocals.
The whole album extends to the 10Hz region with very strong 30Hz material.
Here is "TV Song" by Blue Man Group with some pretty intensive 26Hz to 46Hz material... but seems to roll off pretty close to 26Hz. This is from the DVDV side of "Audio" as my PC isn't setup to play the DVDA side.
I'm curious just what it is "down there" . . . not acoustic instruments obviously . . . is it coming straight from a synth, or from something like a dbx subharmonic synthesizer? Guess I should check the manuals on my Yamaha keyboards . . . it never occurred to me to see how low they'd go since they're never used with speakers that go below 35-40 <g>. I'm pretty sure the P-120 doesn't have output that low, but I just got one of the cheap PSR-295 thingies (for a play around toy) that has all sorts of new "features" . . . maybe I can rattle the walls with it <g>.

Like Thomas's post, instruments do produce all sorts of harmonics with each note and not just the single tone.
Although a lot of what I posted is electronic, PinkFloyd was produced using a simple bass drum while Korn is a bass guitar. Even Breakbeat Era's songs use bass guitar samples...
If the recording equipment doesn't have high pass filter there is quite a bit to be captured. Unfortunately a lot of older stuff does... for example the RIAA vinyl curve actually has a 50Hz ( ) high pass filter. ROb
That looks a lot like what you'd see from an acoustic instrument too . . . with the second harmonic stronger than the fundamental, similar to the distributions in the tuba article. Interesting that the counter locked on the second harmonic (11 db stronger than the fundamental, so I suppose it should). What's curious is that 3rd subharmonic down at 14 Hz (60+ db down, so it hardly matters, but . . .). Where's that coming from? Something in the electronics?
The dbx sub synth would take that 42 Hz fundamental and add a 21 Hz subharmonic of comparable loudness . . . apparently a lot of bands use them (if they can afford the PA to actually make the sound <g>). I gather that it's popular with the car audio "boomers" . . . it's not a style of music that I'm much familiar with, but the technology is interesting . . .
Standard subharmonic syths don't really function that low. From the dbx website.... Synthesis Frequency Range: 26-56Hz (from 54-110Hz input signal)
Many modern musical pieces use what's called a bass 'pedal' synth. They look like a short section of a piano with huge keys, and are usually played with one's feet. They use a MIDI interface and can be programmed to play infrasonics. Any band that uses one of these, travels with a sound system capable of reproducing the output. And even in an outdoor concert it's blatently obvious when they're being played...
