Hans, le joueur de flûte is a ravishing opera, loosely based on the legend of Hamelin’s pied piper popularized notably by the Grimm Brothers, composed by Louis Ganne and premiered in Monte-Carlo in 1906. Rarely recorded, its best rendition is undoubtedly this beautiful 1967 performance with the best French singers of their time, including Liliane Berton and the amazing baritone Michel Dens in the title-role.

Schubert: "Wanderer" Fantasy (2019 edition, 1989 edition), Impromptu Op. 90, Mozart: Piano Sonata No. 11, No. 18, Mussorgsky: Pictures at an Exhibition, Chopin: Piano Sonata No. 3, Others recorded from 1988-2021.

One of the greatest string quartets of the 20th-century, the - 100% Austrian - Alban Berg Quartett remains famous for their unsurpassable renditions of the great Viennese masters. The ensemble notably put on record the supreme Beethoven cycle twice, once in studio, once in the Wiener Konzerthaus. Enjoy large excerpts of these milestone recordings, coupled with late masterpieces of Schubert.

Completists will be happy to own many of the rarities on this four-disc set, including Stevens's first demo session, an unreleased 1970 duet with Elton John, a cover of Fats Domino's "Blue Monday," and several choice live cuts from the late '70s. And it's nice to have an overview of the artist's entire career–from late '60s pop-star wannabe to '70s folk-rock superstar–in one place. But the difference between early Cat Stevens (despite composing hits for others) and post-Tea for the Tillerman Stevens is substantial. The two follow-up LPs were part of a trilogy of brilliance–both musically and lyrically–and any Stevens collection must start there. Nevertheless, surprises and some gems are to be found throughout all four discs–even his most recent recording (as Yusuf Islam) isn't bad. This box set also offers a choice opportunity to reassess a deserving career. (All royalties go to New York City relief victims and orphans and homeless families in underdeveloped countries.)
