"A timely and dynamic picture of the great artist’s travels, to date. Bradley’s book charts a past that also provides many clues and contextual narratives that tell us much about where Parker may be heading."

Lee Rice Epstein, Free Jazz Collective

"Parker’s art and family history get explored at length in Cisco Bradley’s illuminating new critical study Universal Tonality, the first William Parker book that William Parker didn’t have to write himself. Parker appreciates the attention—he called it the story of how he rose 'from rags to enlightenment. Note that I didn’t say riches'—but still encourages musicians to tell their own stories, and not just because critics can be slow to catch up."

Alan Scherstuhl, New York Times

"Excellent and overdue. . . ."

Angus Batey, The Quietus

"The book, while essentially a biography, explains aspects of his musical vision that are exemplified by these recordings. There is an emphasis on vocals and lyrics, and the book goes in some depth with regard to Parker’s interest in poetry and literature, and his love of music from other cultures as well. . . . An important takeaway from Universal Tonality is Parker’s belief that music is in and of itself a revolutionary act, a rebellion against the hatred which he sees as inherent in the current organization of the world."

Todd Manning, Rock and Roll Globe

"Cisco Bradley's insightful, detailed and beautifully illustrated biography is a labour of love. . . . Universal Tonality made me realise that, much as I've always loved his music, I hadn't begun to appreciate William Parker's achievement."

Andy Hamilton, The Wire

"If an antidote to apathy consists of work and proselytizing, then bassist/composer/bandleader, activist and organizer William Parker embodies that antidote. Cisco Bradley has achieved much in simply documenting the extent of his subject’s activities, but he also highlights the spiritual and social dimensions of Parker’s work, all of which is set within music at the free / demanding end of the spectrum, as opposed to the aural balm that jazz in the 21st century often seems to be."

Nic Jones, Jazz Journal

"Parker is one of the foremost practitioners of what is arguably the greatest Black-led American artistic tradition, i.e. jazz, and Universal Tonality casts him in the full light his work deserves."

Patrick James Dunagan, Rain Taxi

"This is long overdue respect and praise for one of the finest and hardest working musicians of the post-war era. William Parker is a national treasure, as this book is a testament to his perseverance."

Tim Niland, Music and More

"Bradley's work, currently only in English, really deserves to be translated into multiple languages." (translated from Italian)

Giuseppe Segala, All About Jazz

"As with the best of jazz biographies, there are excellent descriptions of the music to be found on the key albums of Parker’s various groups. And these vivid words send the curious listener scurrying off to hear the music. . . . The biography is an excellent introduction to William Parker’s music and to his role in the free jazz community in New York and the USA."

Tony Dudley-Evans, London Jazz News

"With sources that include Parker himself, poetry and excerpts from his journals, and insights from friends and peers, Cisco Bradley explains how the artist has maintained his focus. In the process, he discusses free/avant-garde jazz perceptively, helping to clear away hyperbole and misunderstanding."

Mike Shanley, Jazz Times

"The publication of Universal Tonality . . . is both long overdue and richly appreciated. . . . Anyone interested in the state of the free improvising scene needs to read this book."

Robert Bush, New York City Jazz Record

"An instant classic of jazz biography, Universal Tonality is a genuinely inspirational read, testament to the transformative power of art."

Stewart Smith, Tribune

"Bradley's book is a full-on biography, both personal and musical, that never gets lost in academic jargon. . . . The book succeeds in its sheer storytelling of a life, through interviews with Parker and his fellow musicians, who consistently connect Parker's music to his life and to the politics of community. One comes away from Bradley's book quite humbled by a journey that seems never to have compromised on creativity or its possibility to bring more justice to the world. The musician that emerges from Universal Tonality is also a poet and a political activist- or maybe it's clearer to say that we come to see Parker as having erased the lines separating those different roles."

Will Layman, Popmatters

"This meticulously researched, affectionate biography analyzes Parker’s impact as a musician, a composer, and a political revolutionary. An important work that will appeal to jazz historians, scholars of Black history, and music lovers."

Lisa Henry, Library Journal

«“Writing elegantly about the music as well as William Parker's work as an activist and organizer, Cisco Bradley gives a full sense of Parker's centrality to the development and maintenance of the free jazz scene in New York as well as his efforts in presenting the music across the globe. Universal Tonality is a book worthy of its object.”»

Fred Moten, author of, Black and Blur

«“We have precious few monographic works on creative musicians, fewer still on living ones, and none quite like Cisco Bradley's fascinating biography of bassist, bandleader, organizer, and composer William Parker. Bradley situates Parker as part of a historical legacy, skillfully illuminating Parker's career—including his crucial term with Cecil Taylor—as well as the entire underground scene, including the groundbreaking Sound Unity Festival, the enduring Vision Festival, and manifold developments in the New York creative music community. An essential entry in the critical culture reading list.”»

John Corbett, author of, Vinyl Freak: Love Letters to a Dying Medium

"Each of [Parker's] own major projects, including the quartet, Raining On The Moon, Little Huey, and In Order To Survive, is discussed and analyzed in depth; his family history and personal life are documented in detail; and ultimately as full a portrait as possible of William Parker, artist and human being, is painted. Essential reading."
