The numerous instrumental pieces or ‘symphonies’ found in the dramatic works of Rameau are remarkably effective on the harpsichord; the composer himself, with his transcription of Les Indes galantes, invites other musicians to perpetuate this tradition. Seizing on the formidable array of material available in the operas, Pierre Hantaï and Skip Sempé take evident delight in revealing, on their two harpischords, the immense richness of music that is full of surprises and imagination.
