Cistern is an orchestral album by Sacramento-born musician, composer and arranger Jherek Bischoff.

Bischoff began composing and recording Cistern in an empty two million gallon underground water tank under Fort Worden in Port Townsend, Washington.

In an interview Bischoff described how "the vast emptiness of the cistern generates a reverb decay that lasts 45 seconds.

A space which forced Bischoff to slow down, to reflect, to draw on his childhood growing up on a sailing boat - an unexpected journey of rediscovery, from the city back to the Pacific Ocean".

[2] One of the main reasons for this was the " lack of adequate oxygen" for a large group of people inside the water tank.
