Ezz-thetics is a studio album by the George Russell sextet, released on Riverside Records in mid-1961.

[3] In addition to himself on piano, Russell's sextet contained trumpeter Don Ellis, trombonist Dave Baker, Eric Dolphy on alto sax and bass clarinet, Steve Swallow on bass, and Joe Hunt on drums.

[4] It features a radical reworking of Thelonious Monk's standard "Round Midnight" with an extended solo by Eric Dolphy.

[4] The AllMusic reviewer described the album as "a true classic", and added that, "although using ideas from avant-garde jazz, it does not fall into any simple category".

[4] The Penguin Guide to Jazz suggested that it was a good place in Russell's discography for a listener to start.
