The book, characterised by Mehldau as a non-fiction bildungsroman, was published by Equinox in 2023.

Brad Mehldau's career as a pianist and composer began in the early 1990s.^[1] After building a reputation as a jazz improviser, he expanded into other areas such as classical, folk and electronic music.^[1] Mehldau described Formation as "an autobiographical bildungsroman of sorts, tracing my musical and personal formation up until the age of twenty-six".^[2] He recounted that much of the material for the book had been on a computer for at least 15 years, but that he took a long time to identify and form a story based on it.^[3]

Formation was published as a hardback and ebook by Equinox on 15 March 2023, priced at GBP£30 or US$50.^[4]

Reviewers mentioned the book's blending of literary styles,^[5] allusions to a wide range of musical and literary influences^[6] and the disturbing nature of some of its content.^[3][5][7]

Ted Panken, writing in Down Beat, described Mehldau's book as: "an unflinching account of his turbulent first quarter-century, recounting and intersectionally contextualizing, in searing, transparent detail, the circumstances that framed the establishment of the musical relationships and tonal personality that he has elaborated and refined ever since".^[5] The Wall Street Journal reviewer concluded: "Readers of this poignant memoir will discover what Brad Mehldau learned to see during the long course of his formation."^[7]

The book is the first in a planned two-part series.^[1] The second "will focus more directly on the jazz canon itself".^[8]
