I recall reading a comment from Aaron Copland to the effect that he believed that there was undiscovered gems written in those years between the world wars 1 and 2 (roughly 1918 to 1939). And this release certainly confirms that assertion. The 7 pieces here (of which three are receiving their world premiere recordings) represent the years 1926 to 1939, the end of the period following the “War to End All Wars”. The French term “Avant L’Orage” is generally translated as “The Calm Before the Storm”. It is an apt metaphor for the time.

The string trio form, though common, does not seem to have produced the grand stature of some of the music for the more commonly heard ensemble, the string quartet. The trio of Violin, Viola, Cello can arguably be said to not have truly com of age until the twentieth century which would see major works by Schoenberg (1946), Krenek (1949), Wourinen (1968), and Schnittke (1985) to name a few highlights. But these charming little works on this 2 CD set can be thought of as stepping stones in the evolution of the form.

Now I know a lot of pretty obscure repertoire so I was a tad surprised to find that I had only heard of four of the composers represented here: Henri Tomasi (1901-1971), Jean Francaix (1912-1997), Robert Casadesus (1899-1972), and Gabriel Pierné (1863-1937). The other three: Jean Cras (1879-1932), Émile Goué (1904-1946), and Gustave Samazeuilh (1877-1967) were new to me.

Tomasi’s “Trio en forme de divertissement” (1938) is a four movement work with a lighthearted feel. It is structured in classical form. Largely neoclassical in sound. It opens with a Prelude followed by a gentle Nocturne, a pithy Scherzo, and a playful Final. This, surprisingly, is one of the world premieres on this collection. It reveals a composer who deserves a new reckoning and hopefully this recording will help launch it. It is the first of the three world premiere recordings in this set.

The Jean Cras trio of 1926 also follows the four movement format. Cras is one of the names heretofore unknown to this writer.

This work, also in four movements as the previous piece, reveals a more deeply contemplative work Its harmonies are certainly post classical era but essentially familiar. The first movement strikes a serious tone and is followed by a beautiful and contemplative slow movement. The third movement is a playful scherzo like movement followed by a riotously playful and virtuosic finale. It is virtually a symphony for three instruments.

Émile Goué is represented by a three movement work. This is also an unfamiliar name to this reviewer. Again we hear familiar romantic harmonies in a relatively brief (about 15 minutes) piece.

The classical forms of the first tow movements are followed by a scherzo like playful finale. Surprisingly this work as been recorded before.

Jean René Désiré Françaix will be a familiar name to many. His four movement string trio which concludes the first disc is pretty characteristic of his style. He is the youngest of the composers featured here but he crossed paths with most of the prominent French composers of the twentieth century. Harmonically and melodically his work embodies much of the same sound as his older contemporaries. With the exception of the beautiful slow movement these rather hyperactive episodes hold much in common with his previous and subsequent work. Coming in at about 13 minutes this satisfying work whose complexities are subsumed into a friendly, appealing work.

Robert Casadesus was the patriarch of one of the great piano dynasties of the twentieth century. along with his wife Gaby (1901–1999) and son Jean (1927–1972). Robert was also a prolific composer whose output includes seven symphonies and multiple works for piano and orchestra. His trio is a three movement work which opens the second disc on this epic anthology.

This work is among the world premiere recordings on this set. Its brevity relative to the composer’s larger works suggest that this might be a minor occasional piece but this is in fact a compact and deeply serious work. From the opening Allegro con brio we hear a substantive composition. The slow movement contains a playful scherzo like section in the middle before it returns to the more somber tone of its opening. The finale marked “allegro aperto” is, at first a playful finale as one would expect from a classical era symphony but it goes through various moods before it returns to reassert that playful opening. This one makes a case for the further exploration of this composer’s work.

The “Suite en Trio” (1937) is the outlier here, cast in no fewer than 6 movements. The composer, better known as a music critic, was admittedly heavily influenced by one of his mentors, Claude Debussy.

“Trois pieces en trio” (1937 ) concludes this fascinating survey of the string trio format as composed during the interwar period. This three movement work certainly reflects that influence but this is not mere imitation. This is a truly substantive work, the third of the three world premiere recordings here. Each of the relatively brief movements demonstrate a truly gifted composer. Once again the listener will be curious to hear more from this man’s work. We can only hope.

Last and certainly not least is the trio by Gabriel Pierne. He studied with Jules Massenet and was a contemporary of Claude Debussy. As both composer and conductor his profile loomed large on the French music scene. He is the oldest composer represented here and this is among the last of his works.

This trio is in three movements and, like the Casadeseus trio which opens the second disc of this fine collection, it is a weighty, slow moving, serious work. Once again the listener is given to wonder what other treasures ay undiscovered from this curious era of history when the world was awaiting the growing conflicts that resulted in the second world war.

The Black Oak Ensemble consists of Desirée Ruhstrat, violin; Aurélien Fort Pederzoli, viola; and David Cunliffe, cello.

The truly excellent liner notes are contributed by Dr. Elinor Olin, professor of music at Northern Illinois University. The recording by Bill Maylone is up to the usual high standards we have come to expect from producer James Ginsburg’s wonderful Cedille label. And the graphic design by Madeleine Richter echoes the era that gave birth to this great music. This is an epic anthology which fills a great gap in the history of recorded sound. I suppose one must acknowledge the irony of our present moment in history, hoping against hope that history will not repeat itself. Meanwhile much solace can be taken from this lovely collection. This one is a must have.
