Parallel Lives, by the Greek philosopher and historian Plutarch (40/50-120 d.C.), represented a new method of biographical writing based on the narration of a pair of personalities, one Greek and the other Roman, arranged in tandem. This comparative approach showed how similar the two personalities were, while also making their differences clearer. Inspired by this historiographical model, Dissimilar Parallel Lives transfers this perspective to musical programming. Each of the four concerts confronts two coetaneous composers who, despite representing different aesthetic worlds, share some features in their antagonistic difference. A comparative listening of their works intertwined, sometimes created after personal contact or knowledge of their respective compositions, allows the differences of the one spirit of the period and the similarities of opposing aesthetics to be assessed.
