The speakers are moving slowly up and down, as a lung or a heart. The speakers are dead silent, no sound is heard. The movement is created with strong direct current, controlled by automatized volume curve.
The Pumps was part of the solo exhibition Tear Gravity at Galleri Mors Mössa, Gothenburg, Sweden in 2005.
Released on CD by Kning Disk.
