The first musical work for which he is remembered was his role as bassist in the trio Joseph Holbrooke, alongside guitarist Derek Bailey and drummer Tony Oxley.[3] The trio began by playing relatively traditional jazz – they toured with saxophonist Lee Konitz in 1966 – before moving into free improvisation. Bryars became dissatisfied with this when he saw a young bassist (later revealed to be Johnny Dyani) play in a manner that seemed to him to be artificial, and he abandoned improvisation, becoming interested in composition instead. In 1998 the trio reformed briefly, giving two live performances and making recordings.
Bryars's first compositions owe much to the New York School of John Cage (with whom he briefly studied), Morton Feldman, Earle Brown and minimalism. One of his earliest pieces, The Sinking of the Titanic (1969), is an indeterminist work that allows the performers to take a number of sound sources related to the sinking of the RMS Titanic and make them into a piece of music.[3] The first recording of this piece appeared on Brian Eno's Obscure Records in 1975. The 1994 recording was remixed by Aphex Twin as Raising the Titanic (later collected on the 26 Mixes for Cash album). In 2012, the centenary of the Titanic's sinking, Bryars made a new extended version, with film projections by Bill Morrison and Laurie Olinder, that included his four children as a low-string ensemble (viola, 2 cellos, bass) and turntablist Philip Jeck, subsequently released on GB records (BCGBCD21 2013)
Another well-known early work is Jesus' Blood Never Failed Me Yet (1971), which has as its basis a recorded loop of a homeless man singing a musical fragment that the old man had improvised.[4] On top of that loop, rich harmonies played by a live ensemble are built, always increasing in density, before the whole thing gradually fades out. A recording of this work was made in 1993 with Tom Waits singing along with the original recording of the vagrant during the final section.
Bryars was a founding member in May 1970 of the Portsmouth Sinfonia, an orchestra whose membership consisted of performers who "embrace the full range of musical competence" – and who played popular classical works. Its members included Brian Eno, whose Obscure Records label would subsequently release works by Bryars. In one of the label's first three releases, Eno's album Discreet Music, Bryars conducted and co-arranged Three Variations on the Canon in D Major by Johann Pachelbel, which constitutes the second half of the album.
The 1992 composition A Man in a Room Gambling was written on commission from Artangel. Bryars's music is heard beneath monologues spoken by the Spanish artist Juan Muñoz, who talks about methods of cheating at card games (drawing on The Expert at the Card Table by S. W. Erdnase). The ten short works were played on BBC Radio 3 without any introductory announcements, and Bryars wrote that Muñoz hoped they would appear to the listener in a similar way to the Shipping Forecast, "bemused by this fleeting and perhaps enigmatic curiosity."[5]
Bryars has written many other works, including five operas, and many instrumental pieces, among them four string quartets and several concertos. He has written several pieces for dance, including Biped (1999) for Merce Cunningham, as well as works for William Forsythe, Carolyn Carlson, Edouard Lock and David Dawson. In 1981–1984 Bryars participated in the CIVIL warS, a vast, never-completed multimedia project by Robert Wilson, who also directed his first opera, Medea. His cello concerto Farewell to Philosophy was recorded in 1996 by Julian Lloyd Webber. He has also written a large body of vocal and choral music for groups such as the Hilliard Ensemble, the Latvian Radio Choir, the Estonian National Men's Choir, Red Byrd, Trio Mediaeval, Singer Pur, Nordic Voices and The Crossing, whose recording of "The Fifth Century" won a Grammy in 2019. He has written a great deal for early music performers including six books of madrigals, several works for viol consort and a collection of 54 "laude" based on a 12th century manuscript.
Bryars' When Harry Met Addie (a tribute to jazz singer Adelaide Hall and saxophonist Harry Carney) was premiered at the Duke Ellington Memorial Concert at the Queen Elizabeth Hall, London, on 1 May 1999. The piece was performed by the London Sinfonietta Big Band[6] and commissioned by the baritone saxophonist/bass clarinettist John Surman. Cristina Zavalloni sang the soprano and the London Sinfonietta Big Band was conducted by Diego Masson·[7]
Bryars founded the music department at Leicester Polytechnic (now De Montfort University), and was Professor of Music there for several years. He left in 1994 to concentrate on composition and performance. He lives in England, and, for part of the year, on the west coast of Canada.
Since 1986 Bryars has run The Gavin Bryars Ensemble with his preferred musicians, consisting chiefly of low strings. Now, in addition, this regularly includes his children (2 cellos, piano and double bass)
In 2020, Bryars composed Altissima Luce for Sound World’s Coronavirus Fund for Freelance Musicians, a project supporting struggling musicians during the UK’s Covid 19 lockdown. It was included on the album Reflections alongside specially written pieces by other composers such as Nico Muhly, Mark-Anthony Turnage, Evelyn Glennie and Sally Beamish.[8]
In 2023, Bryars collaborated with Goole band Sandra's Wedding on their new EP, "Another Rugby League Town".[9]
Also in 2023, Bryars provided a special guest vocal for experimental composer Bill Vine's[10] work, "Norwich Under the Water".[11] The piece premiered at Norwich Cathedral in August 2023.
