Right off the bat, the "bio-" is implied by a wet, squishy sound and the "-mechanical" by a constant low-pitched thrum. Later on, the thrum is joined by beeps that sound like they might be coming from some kind of control panel. I think I hear footfalls as well. I picture a group of space travelers walking through muck on a spaceship they've boarded, only to realize to their horror that the muck is living tissue. The track suggests a sort of creepier version of certain scenes from the Star Trek: The Next Generation pilot, "Encounter at Farpoint." I could easily imagine using this track for certain kinds of CthulhuTech, Delta Green, Star Trek, Star Wars, and Dr. Who scenarios. If you're setting an RPG scene in a venue where creepy biomass and high technology meet, consider using this track to add immersion.

Another excellent ambient track.

(SPOILERS AHEAD) Perfectly suitable the scenario "Dawn of the New Age" from the "The New Age" minicampaign included in the "Delta Green" sourcebook, but could also be used in other scenarios that include mi-go locations, like "Think Tank", included in the out-of-print "End of the World" from Triad Entertaintment.
