1 is a studio album by Fats Navarro and released posthumously by Blue Note Records.

Material for the album came from record dates with a variety of musicians including Tadd Dameron, Ernie Henry, Wardell Gray, Charlie Rouse, and Bud Powell.

"[1] The authors of The Penguin Guide to Jazz Recordings awarded the album a full 4 stars and a "crown," calling it and its companion volume "one of the peaks of the bebop movement and one of the essential modern-jazz records.

"[5] Author Tom Piazza stated that the albums "show instantly what set Dameron's work apart," and commented: "Among bebop dates, these were really something special, full of carefully worked-out ensembles, introductions, and codas, yet still with plenty of stretching room for the soloists.

"[6] Saxophonist and writer Benny Green noted Dameron's "ravishing tone" and "precise delivery," and called the recordings "a reminder of the grace of one of the earliest modern pioneers, a grace that was precocious because in the 1940s modernists had still not formulated their own conventions.
