Here is my contribution to the May 2018 Basschat Composition Challenge, inspired by a picture chosen by last month's winner: Rikki1984.
The ruined vestiges of a once-powerful empire, long-since engulfed by the ocean's depths. Joined, many centuries later, by a now-rotting hulk, another failure of mankind, another symbol of the ephemeral nature of 'power'.
Quite complex, really, combining deceptively simple percussive elements (cymbal swells, taiko drums and more...) with more exotic timbres, such as sitars and operatic voices, (very...) deeply underpinned with several drones, aptly generated by a software synth, 'Atlantis' (the name is not a coincidence, but the appropriate timbre of the sounds certainly is...). The ocean's voice is expressed through renderings from hump-backed whales; these may well be leagues away, as their tones carry over vast distances under the surface.
Thanks for listening, if you already have; if you're about to, enjoy.
