15 Seconds is part of an ongoing series of site specific performances by musician and sound artist Lauren Sarah Hayes. Evoking the unique aural and visual qualities of the iconic Hamilton Mausoleum, boasting the longest echo in any man-made structure, her work offers an intimate concert experience, where the music is formed out of a relationship with the unique architecture of the building.  Accompanied by sonically responsive flash light bulbs, the acoustic and visual possibilities of this remarkable landmark are truly revealed.
