Sebastian Durán (born in 1989) began to study classical singing at the age of 15 (alongside his cello- and harp studies) in his home town of Kristianstad, in the south of Sweden.

Since graduating from the Malmö Academy of Music in 2013, and the University College of Opera in Stockholm in 2016, Sebastian has been working in opera companies and concert venues all around Europe such as the Malmö Opera, the Royal Opera in Stockholm, Arctic Opera, Den Fynske Opera, Copenhagen Opera Festival, Oslo Opera Festival, Aldeburgh Festival, National Philharmonic of Ukraine, and Vadstena-Akademien.

Past roles includes, among others, the title roles in Don Giovanni and Hamlet, Demetrius in A Midsummer Night's Dream, Guglielmo in Così fan tutte, Hans in Comedy on the bridge, Marullo in Rigoletto, Morales in Carmen, The Crow in Snödrottningen, and Jack Worthing in an operatic version of The Importance of Being Earnest (composed by B Tommy Andersson) which premiered in Sweden to great acclaim in the summer of 2017.

He is also a sought after concert- and oratorio singer in works such as Ein Deutsches Requiem by Johannes Brahms, St Johns Passion and the B-minor mass by Johann Sebastian Bach, Carmina Burana by Carl Orff, and A God disguised by Lars-Erik Larsson.
