One Atmosphere is an album composed entirely by Texas-born saxophonist Julius Hemphill.

Tzadik Records released the album in August 2003.

In a review for AllMusic, Thom Jurek called the opening track "one of [Hemphill's] most compelling pieces," while "Savannah Suite" "concentrates on the interrelationships of the various kinds of lyric tones and rural themes that obsessed Hemphill throughout his life."

Jurek went on to describe the four-part "Water Music" as "easily the most monumental and breathtaking piece of music Hemphill ever composed... a labyrinthine work that is the epitome of Hemphill's musicality and deep, almost reverential dedication to the wind family.

"[4] Jeff Stockton of All About Jazz noted the music's "combination of blues roots and classical formalism," and wrote: "Tzadik and producer Ehrlich have performed a service documenting and making this music of Julius Hemphill available.
