There are conventional pianists and unconventional pianists, and then there’s Víkingur Ólafsson. A string of original albums is testament to his individual way of programming, by coupling Debussy with Rameau, for instance, or looking at Mozart — who the Icelandic pianist describes as a late bloomer — through the lens of his 18^th-century contemporaries. And then there’s the sheer chutzpah of an artist choosing to break out of the commercial hamster wheel and devote the entire 2023 – 24 season to a six-continent odyssey playing just one work: Bach’s Goldberg Variations.
