Billain (born Adis Kutkut) is a Bosnian drum and bass producer, DJ and sound designer from Sarajevo. He is mostly known for his distinctive style within the neurofunk genre and his collaborations with Frenkie and Edo Maajka.

Billain was influenced as a pre-teen by the Bosnian War. During the four-year lasting Siege of Sarajevo he began to draw and later discovered graffiti and created his first hip hop productions

In search of new possibilities to express his feelings originating in the siege, at first Billain taught himself how to produce techno music and later neurofunk. Before he released his first music, Billain joined the drum and bass collective Kontra which organised many drum and bass events in Sarajevo with Djs like Matrix & Optical, Teebee, Stakka & Skynet and Konflict. His music has been played on BBC Radio 1 and has been featured on UKF Music
