Arsenica

Arsenica formed in Buenos Aires when Alan Boguslawski met guitarist Sergio Chotsourian. They were joined by bassist Mariano Castro and drummer Facundo Piccione. The group's early work had a certain atmospheric quality that drew listeners in, though it wasn't always an easy fit for mainstream radio.

Their 2010 album included the track 'Balada Al Cielo,' which became one of their better-known songs. Other pieces like 'FSMD' and 'Karma' showed their range, moving between rock textures and more reflective moments without settling into a single predictable pattern.

Some critics found their sound too experimental or their lyrics too introspective for broad appeal. But they kept working, releasing albums like 'Nube Negra' in 2007 and building a following that appreciated their particular approach.
