IAN Carr, who has died at the age of 75, was something of a jazz all-rounder. For several decades, the Dumfries-born trumpeter was at the forefront of the contemporary jazz scene in Britain, both as a player and a teacher. But his talents extended further: he was also a gifted writer, composer, bandleader and broadcaster. His legacy includes his recordings with pioneering groups Nucleus and the United Jazz and Rock Ensemble, the book regarded as the definitive biography of Miles Davis, a pair of acclaimed biographical documentaries for Channel 4 on Davis and Keith Jarrett, and two Radio 3 series on the same subjects.

Although he was born in Scotland, Carr grew up in the north-east of England. He studied piano from the age of 12 and began to teach himself the trumpet seven years later. Despite reaching the finals of the Carroll Levis Discoveries talent show at the age of 19, he decided not to pursue a music career, and instead chose to follow his literary inclinations by reading English at King's College, Newcastle.

University was followed by National Service in the Royal Northumberland Fusiliers, from 1956-58, and then two years spent "wandering around Europe".

When he returned to Newcastle, Carr took up a teaching job and became very active on the local music scene. In 1960, he joined the EmCee Five led by his brother, Mike, and two years later he moved to London where he joined flautist Harold McNair's quintet before forming his own successful quintet with the tenor saxophonist Don Rendell. Before its demise in 1969, the Rendell-Carr Quintet recorded five albums, which, although influenced by Miles Davis's work of that time, were otherwise different to anything else on the market.

In 1969, Carr's interest in Davis's jazz-rock electronics inspired him to form Nucleus, a highly original band which almost immediately won the 1970 Montreux Festival Jazz Competition and consequently played at the Newport Jazz Festival in the USA. Carr led the internationally renowned band on and off for almost two decades, and it produced 13 albums, most notably Elastic Rock (1970) and In Flagrante Delicto (1978).

Carr, meanwhile, also recorded with some of the most avant-garde players and composers, among them Keith Tippett and Michael Garrick.

Carr's CV also includes the pan-European jazz group, the United Jazz and Rock Ensemble, which he co-founded in 1975. Based in Germany, it assembled annually for 20-odd years and regularly played to sell-out crowds across Europe - despite having been originally formed just to play on television. Its first album, Live in Schultzenhaus, sold 60,000 copies in its first year and went on to become Germany's best-selling jazz record ever.

During the 1970s, Carr also developed his talent as a writer. His writing career began in 1973 with the publication of Music Outside, an examination of the British avant-garde movement in the 1960s. He followed it with the acclaimed biography of Miles Davis in 1982 which was re-published in a revised edition in 1999, after Davis's death. Other notable books included his 1991 biography of Keith Jarrett and Jazz: The Essential Companion, revised in 1995 as Jazz: The Rough Guide, which he co-authored.

Diagnosed with colon cancer in 1983, Carr underwent several operations but recovered in time to undertake an intensive tour of South American with Nucleus for the British Council in 1984. After he disbanded Nucleus four years later, he led the 11-piece Orchestra UK, an all-star outfit featuring the saxophonists Evan Parker and John Surman as well as the pianist Stan Tracey.

Broadcasting gave him another medium for sharing his enthusiasm and knowledge of his subject, and he became a regular presenter on Radio 3. He was also an inspiring teacher, and, in 1982, became an associate professor at the Guildhall School of Music and Drama. It was to the Guildhall that his scores - among them the acclaimed Old Heartland, an evocation of the Northumbrian landscape scored for string ensemble and jazz soloists - were donated.

Ill-health and tragedy dogged Carr. His first wife died in childbirth (he was divorced from his second), and, after beating cancer in the 1970s, he was prone to fits of depression. A series of strokes in his past decade led to the early onset of Alzheimer's Disease which was in evidence when, in 2006, he won the BBC British Jazz Award for services to jazz. He is survived by his daughter.
