Esmeralda composed a unique a cappella choral piece for Olafur Eliasson’s Ice Watch called Ice Lament. Esmeralda assembled a choir of over 40 local singers. She conducted these singers during the site-specific performance which created rich sound landscapes by singing into the blocks of ice.

Ice Watch is a public artwork by Olafur Eliasson and Minik Rosing that was created in London on the occasion of COP24 in Katowice Poland and was originally created in Paris on the third anniversary of the Paris Agreement.
