About us

Terra Invisus are a contemporary music trio, dedicated to pushing musical and sonic boundaries through free improvisation, and the performance of new commissions and contemporary works. Comprised of Milda Vitartaitė (piano), Alex Lyon (clarinets), and Rebecca Burden (cello), they draw on their individual musical experiences to curate forward-thinking live performances and collaborations.

The trio is actively engaged in collaborations with both young and experienced composers, being passionate about performing and recording new music, as well as free improvisation.

Recent highlights include a performance of the chamber opera ‘Outlier’ by Josh Kaye at Tête à Tête: The Opera Festival 2022. Terra Invisus is a recipient of Colin Blythe Bursary and the winner of Gladys Puttick improvisation competition 2022 at Trinity Laban.


Alex Lyon is an eclectic, cross-genre musician and composer based in South East London, specializing in contemporary music and free improvisation on clarinet and bass clarinet. Her solo work blends minimalism and traditional music influences with extended clarinet technique.
She is an adept collaborator and improviser across contemporary classical, free jazz, and traditional music, shaped by her studies at Sheffield University and Trinity Laban Conservatoire. She has performed at many venues across the UK, such as Kings Place, Woolwich Works, and the Brighton Dome with the Brighton Philharmonic Orchestra.
As a member of the award-winning global folk collective, Mishra, Alex first featured on their second album, "Reclaim" (2021), and since then has performed at festivals such as Celtic Connections, and Cambridge Folk Festival, as a clarinettist and vocalist. She also regularly performs and composes with Indian Classical vocalist, Deepa Shakthi.
In the contemporary classical music scene, Alex works alongside many composers, premiering new works regularly both as a soloist and a member of contemporary classical trio, Terra Invisus.

Rebecca is a cellist based in South East London. She is a member of orchestras and ensembles such as London Contemporary Orchestra, London Choral Sinfonia, and Standard Issue.
As well as an excellent classical cellist, Rebecca also considers herself a collaborative composer, working closely alongside composers to create new art and experiences for diverse audiences. Her practice has taken her from clubs, abandoned offices and hotels frequented by witches, to the Barbican, the Athens Acropolis and Hamburg Elbphilharmonie. She recently graduated from the Trinity Laban Conservatoire of Music and Dance, where she was awarded the Montague Cleeve and Headley Trust scholarship.

Milda Vitartaite is a Lithuanian pianist and composer. Having started piano and composition lessons at the age of 12, Milda gained her Master’s Degree in Piano Performance at Trinity Laban Conservatoire of Music and Dance, UK, under the guidance of Douglas Finch, where she also had opportunities to shape her artistic expression with such celebrated artists as Pascal Roge and Martino Tirimo.
In recent years, Milda has emerged on the contemporary music scene as a dynamic and fervent interpreter of modern piano repertoire with a passion for bringing new works to the forefront of the classical music scene. Her commitment to new music led to numerous collaborations with emerging composers, premiering both chamber and solo pieces written for her.
Milda’s national debut as a composer came with the dance theatre work 'Plastic Bag Odyssey', which enjoyed acclaim in various Lithuanian festivals during 2020 and 2021. Since then, Milda’s works have been performed in different venues across London, including The New Lights Contemporary Piano Festival 2023.
