Amine and Hamza M'raihi are two Tunisian musician brothers, playing respectively the oud and the qanun, the two major instruments of the classical Arabic music.

Since a very young age, the brothers were raised with classical Arab music which allowed them to develop an extensive mastery of their instruments. They have since evolved into diverse musical traditions including classical western music, jazz, flamenco, Indian, Persian music and many others.

Their latest project, The Band Beyond Borders, dives even deeper in modern harmonies, hypnotic grooves and profound feeling, and features french-indian tabla player Prabhu Edouard and swiss-indian violinist Baiju Bhatt, as well as swiss saxophonist Valentin Conus. This concert is in association with the Pro Helvetia Swiss Arts Council.

The Quarter comprises four distinct venues situated at the iconic Royal Opera House. Live At The Quarter (a live music venue), Drink at The Quarter (a cocktail bar), Café at The Quarter (an all-day café), and Dine at The Quarter (an al-fresco restaurant).
