Nervous Cop

American experimental/free improv/noise-rock band formed in the early 2000s by two drummers, Zach Hill from Hella and Greg Saunier of Deerhoof. After a year and a half of private studio sessions and jamming as a "twin-drummer" duo, Nervous Cop expanded to a quartet, with John Dieterich's electronics and Joanna Newsom (of The Pleased) on harp.

In 2003, Nervous Cop released the band's debut self-titled album, available on CD and in digital formats via 5 Rue Christine, a sublabel of 5 Rue Christine. Nervous Cop occasionally performed as a supporting act on Deerhoof tours. Subsequently, the ensemble decreased live activities and went on an unofficial hiatus, most likely as Zach Hill became preoccupied with hugely popular Death Grips.

In 2017, Nervous Cop returned with a new lineup, producing a follow-up (yet again, self-titled) — an 18-minute improvisational jam released as part of Deerhoof's 5 Rue Christine program. The digital download was initially available exclusively via CASH Music platform (a non-profit organization established by Kristin Hersh (of Throwing Muses), Donita Sparks of L7, and Jesse von Doom in Portland, Oregon).
