Mezzo-soprano Daniela Mack presents a deeply personal exploration with Sur, an album shaped by memory, identity, and the enduring pull of home. Inspired by a vivid childhood recollection - listening from the back seat of her father's car - Mack traces her first encounter with the electrifying sound world of Astor Piazzolla. His music, brimming with colour, grit, and intensity, left an indelible mark, one that continues to resonate in her artistry today. Known for her versatility across the operatic spectrum, Mack finds in Piazzolla's reimagined tango a natural meeting point between classical discipline and expressive freedom, bringing to these songs both technical finesse and emotional immediacy. As an Argentine artist living abroad, Mack reconnects with the spirit of Buenos Aires through music that invites vivid storytelling. Each piece unfolds as an intimate vignette, enriched by arrangements of her collaborator JP, whose work honours Piazzolla's legacy while adding a distinctive, personal voice - including his tender Dulce suenos. Together, they create a sound world that is at once nostalgic and immediate, rooted in tradition yet alive with reinvention - an invitation to experience music that, in it's depth and universality, speaks to all. This album marks Daniela Mack's debut on PENTATONE.
