Born in 1955 Algerian composer Thierry Alla studied at the Conservatoires of Tours and Bordeaux. Published in 2012  Rouages for Alto Saxophone and Electroacoustic Device is an example of the composer's prolific contributions to the modern genre. Alla has composed significantly composed for all Saxophones and has experimented with a variety of software to recreate and produce sounds and synthesis techniques. These two combined have created many successful modern works including Rouages of which a typical performance lasts around 5 minutes and 10 seconds. The Saxophone demonstrates use ofchromaticism extended techniques and complex rhythms among other features whilst accompanied by an electronic part helpfully recorded on a CD. For all advanced saxophonists aspiring to play a range of repertoire Alla's Rouages is essential.
