Aileen (b.1994) is a Scottish composer, accordionist and arranger based in Glasgow and enjoys a varied career as a freelance musician. Her music is cross-genre, infused with the ornamentation, energy and colours of the Scottish folk music she grew up playing learning the accordion. Her music is often influenced by nature and folklore, as well as finding inspiration in current social and political affairs she is passionate about such as climate change, equality and politics.

Aileen has worked with and been commissioned by many of the UK’s ensembles such as The London Philharmonic Orchestra, The Red Note Ensemble, The Nevis Ensemble, The Michael Cuddigan Trust, The Edinburgh Quartet, The Brodick Quartet, The Hebrides Ensemble and The Psappha Ensemble.
