Joanna MacGregor is not your typical classical concert pianist. For starters, she completely rejects the notion that concert music is superior to other genres. “One critic has described her as ‘exhilaratingly, recklessly democratic’ in her musical tastes, because the London-born pianist has no qualms about mixing musical genres in unconventional and sometimes unlikely ways.” But don’t call her concerts “crossover”. MacGregor’s programs may mix a few musical metaphors, but never in a way that demeans the intelligence of either the music or her audience.
