Several dictionaries of English language define the word “duality” as “a quality or state of being two”, “combining two different things”, “having two different parts”. The word encapsulates precisely the aim and the essence of the album of the young Slovenian classical guitarist Aljaž Cvirn: namely, his manifold approach to his instrument and the classical repertoire. The album Duality is, thus, an insight into multifaceted notion of music for a musician, who – active both as a soloist and as a chamber musician – focuses on the musical (re)consideration of the established pillars of the Romanticism: Johannes Brahms, Felix Mendelssohn Bartholdy and Franz Schubert.
