Baudelaire's mysterious L'invitation au voyage, not in its famous setting by Henri Duparc, but in a setting by Alphons Diepenbrock (1862-1921). The song comes from the Diepenbrock Anniversary box set (more HERE), the most comprehensive collection of his non-symphonic music. Highly recommended. Riccardo Chailly conducted a lot of his music with the Royal Concertgebouw Orchestra. I discovered Diepenbrock when his Im grossen Schweigen was paired with Mahler 7th in Chailly's Mahler RCO series. The photo above shows Diepenbrock (left) with Mahler and Willem Mengelberg on the Zuiderzee in 1906.
The singer on this recording is Aafje Heynis, well known for her Bach. She died last December, aged 91.
