"Among the plethora of bands purveying the ‘Balkan sound’ few have taken the trouble to properly immerse themselves in Central Europe’s rich variety of musical traditions.

Playing with maximum energy and a great sense of fun they soon had a lively Valley Fest audience enthralled and even dancing despite the heatwave temperatures of a steaming afternoon."
