I have always found the sound of fog horns uniquely compelling. Perhaps the song of whales comes close, but the unwavering and slowly unfolding music of the fog horn will hold me entranced for hours on any coastline where I should chance to hear the sound.
So when I first came across Ingram Marshall's Fog Tropes on a compilation of various pieces put together by John Adams , I was intrigued. One listen, and I fell in love .
I subsequently acquired an equally entrancing early version of the work, also conducted by John Adams on Ingram's own New Albion CD ( NA002CD) featuring the work along with Gradual Requiem and Gambuh I.
Ingram is an assured master of the ambient soundscape. His work often resembles that of Brian Eno with whom he shares a strong structural underpinning for even their most ethereal works. But, unlike Eno, Marshall is more apt to make use of conventional 'classical' instrumentation, albeit in a heavily electronically treated form.
A brass sextet plays an important role in Fog Tropes, providing melodic and coloristic counterpoint to the wailing of the also electronically treated fog horns. He also introduces voice, again in a strictly coloristic mode, to give a human touch to the electronic fog. It does so admirably.
In some ways Fog Tropes resembles the famous Ives' Unanswered Question. There is a low register, relatively unvarying, foghorn-derived bass over which brass and voice pass repeated musical phrases. But it is more multitextured than the Ives' piece and consequently has a different feel. If Ingram was trying to paint a sound portrait of a fog bank he succeeds admirably, but the work has a resonance that goes way beyond those pictorial associations.
I often compare it to the Eno work, Ambient 4: On Land, and it shares many qualities with the pieces on that album. But unlike the Eno works, there is a sense of progression, climax and resolution that separates it from the more static ambient pieces. Fog Tropes tells a story as well as representing a state of nature, and that gives it one extra level of meaning.
A wonderful work.
