The Callum Au Big Band

Callum’s longest-standing ensemble is his eponymous big band. Founded in 2009, the band has performed at clubs and festivals around the country, and recorded with many top UK jazz artists including Emma Smith, Anthony Strong and Nigel Hitchcock. The band’s members are hand-picked from the very best of the London jazz and commercial music scene.

The band released its first album, ‘Something’s Coming’ in January 2013. Recorded at Angel Studios in London by Grammy-winning engineer Steve Price, the album features a selection of Callum’s compositions and arrangements, including the West Side Story Suite, a six-movement extended piece for contemporary jazz orchestra based on some of the most famous melodies from Leonard Bernstein’s musical.

Something's Coming
Far Beyond The Stars


In 2019, Callum began a new collaboration with jazz vocalist Iain Mackenzie inspired by the music of Marty Paich and the Dektette. Members of the big band, complete with additional French horn and tuba, accompany Iain in a selection of songs originally recorded by Mel Tormé in 1960 on the seminal album “Swings Shubert Alley”. More recently, Callum added some of the charts from “Ella Swings Lightly” to the Dektette’s repertoire, to feature the wonderful jazz singer Emma Smith.

The band also performs some of the most popular jazz instrumental music of the era – from Thelonious Monk, Dizzy Gillespie, Count Basie and Art Pepper; and a couple of originals too.

The group has performed in top jazz clubs around the country to critical acclaim.
