Seine is an avant-garde band known for its unique blend of musical styles that often combines elements of folk, punk, and experimental music. The band emerged from the collaborative efforts of Croatian musician Ivan Ščapec, who was initially the guitarist for the band Vlasta Popić, and Dimitrij Petrović, who is known for his work with the Serbian band Straight Mickey and the Boyz. Together, they create a sound that is at once both raw and poetic, characterized by Ščapec's distinctive singing and intricate guitar work, alongside Petrović's versatile percussion.

The music of Seine is marked by introspective lyrics and often tackles themes of personal and social introspection, offering a rich tapestry of introspective storytelling set against a backdrop of innovative soundscapes. With releases like "Naizust" and "Riječ," Seine has continued to build upon their reputation for crafting thought-provoking music that defies easy categorization. Albums like "22," "Nebo," and "Sno sna" further showcase the band's evolution in sound and their commitment to pushing the boundaries of genre, while maintaining a profound emotional connection with their listeners.
