Resonant Earth: Collective Ritual at Suli An on 9 September - 24 musicians with three tubas, a cimbasso and a zurla in one ensemble

Twenty-four musicians will play at once at Suli An on 9 September, in the second Skopje edition of "Resonant Earth: Collective Ritual", Jordan Kostov's project. The first edition was held in the same setting, and in between the cycle passed through Paris, Berlin and London, so this is not an attempt from scratch but the continuation of a form that has already been worked out.

The line-up is what makes the event unusual. It has three tubas - Micko Damnjanovski, Aleksandar Ninic and Viktor Grizev - plus a cimbasso played by Nick De Carlo, Jovan Miloshevski's contrabassoon and two bass clarinets. That is a quantity of deep brass and woodwind rarely assembled outside a symphony orchestra. Alongside them come Gjeljo Despotovski on zurla, Vesna Mikic on harp, Yasser Bajat on kemenche and setar, Krume Stefanovski on hang drum and a whole row of percussion, while Kostov adds trung, taishogoto, accordion and vocals. Five vocal performers close the circle.

The organisers call it neither a concert nor an exhibition, but a collective ritual in sound, space and movement. Ten more artists bring their own work into the different chapters of the evening, with shadows and clouds as a stage element inside Suli An, and Marija Milosheva's installation "The Fly Flies With Diamonds" is also on display. The Ottoman inn, with its walls and inner courtyard, is an acoustically unpredictable space, which for an ensemble like this is part of the material, not an obstacle.

The event is on 9 September at 8pm at Suli An in Skopje. Tickets cost 1,200 denars through karti.com.mk. No ensemble of twenty-four people plays the same thing twice, which means this evening will not have a repeat.
