Andrew Lewis is an award-winning composer and an internationally recognised figure in the field of acousmatic composition. He studied composition with Jonty Harrison at Birmingham University (UK), and as a student there was part of the original line-up of BEAST at its founding in 1982. He worked with BEAST throughout the Eighties and early Nineties, helping to establish the group as a leader in acousmatic performance on the UK and international scenes. Along with acousmatic music, his more recent work includes more music for orchestras and ensembles, but retains a strong interest in the phenomenon of sound as raw material and the use of technology to realise new kinds of musical ideas. He is especially interested in spatial sound, in the relationship between 'real-world' and 'abstract' sounds, and in the phenomena of aural perception as part of the creative process.

Andrew Lewis' music rose to fame through several awards, notably the 1986 EMAS/PRS Prize for 'Storm-Song'. He garnered accolades at venues including Bourges (1997 and 'Euphonie d’Or' in 2004), Valencia (2001), São Paulo (2003), and Montpellier (2016, 2018). His 'Tempo Reale' was featured at Wigmore Hall in 2004 by Sir Peter Maxwell Davies. His compositions have resonated with top artists like the BBC National Orchestra of Wales and Kreutzer Quartet. Noteworthy projects are 'LEXICON', which had over 1700 live viewers, and 'Fern Hill', commissioned for Dylan Thomas' centenary, aired on BBC Radio 3. In 2016, a Leverhulme Fellowship led him to create 'Lebenslieder'. He was recognized at ISCM World Music Days in 2019 and collaborated with UPROAR Ensemble. His works are recorded in collections like 'Miroirs obscurs' and published by Composers Edition and Ymx média, Montréal.
