The Eleventh Hour is an album by British saxophonist and improvisor Evan Parker's Electro-Acoustic Ensemble recorded in November 2004 and released on ECM the following year.

[1] The AllMusic review by Thom Jurek awarded the album 4 stars stating "There is a lot going on as violin, soprano saxophone, percussion, and piano all fall together, but as the sounds are treated and added to electronically, they have an air of space and separation that creates an immense space for the listener.

"[2] The authors of the Penguin Guide to Jazz Recordings wrote: "Eleventh Hour is a dark and foreboding work, packed with black energy...

It's an astonishingly powerful record, and a perfect development to the language of this essential group.

"[3] Writing for All About Jazz, John Kelman commented: "While The Eleventh Hour is not an album for listeners tied to conventional musical approaches, it remains striking and strangely compelling, if for no other reason than it demonstrates just how far the creative mind can expand even well-established concepts into completely new territory.
