Hard to believe it’s been done, but it has, more than once, as a search on YouTube will quickly reveal: Carl Orff’s “profane cantata” Carmina Burana, with duo pianists deputizing for an orchestra of symphonic proportions. But the percussion section remains intact. As so often in Orff, the noisemakers have a huge role to play, at the threshold of silence as well as the gates of pandemonium. (Audiophiles used to love to spin Carmina Burana to show off their sound systems. Good choice.) The headliners for these concerts are the photogenic brothers—no, not twins—Lucas and Arthur Jussen. Artistically versatile, technically unassailable, they’re rising fast, especially in their native Netherlands. No doubt it’s their personal réclame that explains this blowout at Maastricht’s crown-jewel conference center and exhibition space. MECC is promising an “immersive” and “mesmerizing” experience involving “a large choir, six percussionists, and a selection of international top soloists,” as well as “a major children’s choir from Maastricht.” Do any of these people have names? Is there a conductor? (There had better be.) The promo sounds more seat-of-the-pants than “world class” (that ghastly shibboleth), but the proof is in the pudding. And the Jussens really are something. —Matthew Gurewitsch
