Aritmija is based on a guitar duo, formed by two guitarists, composers, multi-instrumentalists and guitar teachers Tilen Stepišnik and Šemsudin Dino Džopa, from Ljubljana, Slovenia. In the last 15 years Aritmija has performed over 500 concerts in Slovenia and abroad (Switzerland, Germany, France, Italy, UK, Austria, India, Uzbekistan, Belgium) and released 3 CDs. The style that best describes the music of Aritmija would be world-music, a mix of traditional music from the Balkan region, rock, jazz and flamenco, which the two guitar players skillfully combine in their own compositions.

Aritmija’s live line-up usually consists of two guitarists. Frequently, however, Aritmija broadens its musical spectrum with percussions and violin and most recently, with exquisite musicians from India, vocalist Sabiha Khan and virtuoso Vinayak Netke on the Indian percussion tabla.
