Karl Mattar aka Interbellum is a songwriter from Beirut, Lebanon. He introduced his music to the world 2013 with an EP under the nom de guerre Charlie Rayne, which Goethe Institut described as «intricate» and «dense» and which catapulted him into a 50-date tour of Europe and several festival appearances.
In 2016, Mattar branched out into more layered textures and thick, rhythm-driven compositions in his new project Interbellum. Throughout the summer, he will be performing concerts in Germany in the run-up to the release of a new album, currently slated for a fall 2018 release. This solo performance at Donau115 will feature songs from this forthcoming album, as well as deeper selections from his work as Charlie Rayne.
