URHO & Urban Horns


VIDEO: Eröffnungskonzert Helsinki Festival (2013)

Description

Listen up! There's more to the city than noise pollution. This musical ode to Helsinki kicks off with the German Christof Schläger's urban horns. Custom-built for Helsinki, they will announce the start of the festival at Kauppatori Market. Icebreaker Urho takes part in the horn concert as well. At the same time, in another location, a fleet of hot air balloons will take to the skies above the city. Luke Jerram's Sky Orchestra invites everyone to hear a concert from above. The hot air balloon orchestra will glide across the city skies and greet the gathered crowds at Kauppatori.
