Dee Byrne (alto sax) is a composer and improviser working in both jazz and experimental music (acoustic and electronic). Since 2019, explorating deeper into the area where structured, composed material meets with free improvisation, Dee came up with a bunch of new music, which has since been recorded with two ensembles: her new sextet Outlines, with an album on Whirlwind Records 2023); and UK/Swiss collaborative sextet MoonMot, with an album due for release on ENJA in 2023. Dee has been playing in mainland Europe as well as the UK, both with MoonMot and European quintet Ydivide (led by Swiss drummer Clemens Kuratle). She is also active with UK/Swiss trio Motherboard Pinball, long-standing duo electro-acoustic duo Deemer with Dutch sound artist Merijn Royaards; and with the London Improvisers Orchestra.

Since 2013 Dee has worked with improvising baritone saxophonist Cath Roberts under the Banner of LUME, a platform for improvised music based in London. Dee and Cath play in a regular duo and will be performing at the Summer Bummer Festival in Antwerp in August 2023.
