Repetitor is a Belgrade-based alternative rock / garage punk trio formed in 2005. The band consists of Boris Vlastelica (guitar and vocals), Ana Marija Ćupin (bass and vocals), and Milena Milutinović (drums).

The band emerged as part of the so-called “new Serbian scene” and quickly gained attention for their extremely energetic and raw live performances, blending garage rock, post-punk, noise rock, and post-hardcore influences. Their first single, “Ja” (“Me”), became an underground hit and received extensive airplay on Radio B92.

Their debut album, Sve što vidim je prvi put (“Everything I See Is for the First Time”), released in 2008, marked their breakthrough on the regional alternative music scene. They later released:

• Dobrodošli na okean
• Gde ćeš
• Prazan prostor među nama koji može i da ne postoji

Repetitor is widely regarded as one of the strongest live bands in the Balkans and has performed throughout Europe, as well as in Russia and China, at festivals such as Sziget Festival, EXIT Festival, Eurosonic Noorderslag, and INmusic Festival.

Critics often compare them to bands such as Nirvana, Sonic Youth, and The Stooges because of their raw sound and intense energy, although Repetitor is generally considered a highly authentic and distinctive band within the regional music scene.
