Hélène Grimaud’s new solo disc, titled Resonances and newly released on DGG, comprises the recital program with which she has been touring this past season. It features three piano sonatas, each from a different period. So, what do Mozart, Liszt, and Berg have in common? Grimaud sets out to demonstrate, with high-voltage, quasi-operatic readings that are clearly meant as a departure from the typical anthologies in which three or four works by the same composer are presented, often as part of a “complete” traversal of a body of works.
