Deep beneath the roads and houses of West London, a sinister menace lurks: colossal fatbergs – huge congealed masses of domestic waste and oil, hard as concrete and oozing with menace. This piece of music is a subterranean journey through a landscape of twisting pipes, dripping water, scuttling rats and... emerging from the gloom... the vast and glistening monsters of the deep. The music builds to a triumphant, towering climax, before shuddering back into the darkness and slime. This work (for standard British brass band) was developed for Fulham Brass Band as part of the Adopt a Music Creator project, funded by the PRS Foundation and the Philip and Dorothy Green Music Trust, and run by Making Music, in partnership with Sound and Music.
