During the 18th century, it was not uncommon for enlightened princes with musical pretensions to commission works from their court composer and then affix their own names to the title pages. But in the recently solved riddle of the so-called Pergolesi/Ricciotti ''Concerti Armonici,'' the case seems to be just the reverse. These six works, written in the contrapuntal sdyle of the late Baroque, were long thought to be the work of Giovanni Battista Pergolesi, largely because handwritten copies of the score found in various collections attributed the set to the Italian composer.

For several decades beginning in the 1950's I Musici was the leading ensemble specializing in Italian Baroque music, and their performances were standard-setting in their time. Their recordings still hold up exceptionally well even though approaches to early music, driven by the period instrument revolution, have changed somewhat since then.

Known by and large for his seemingly inexhaustible supply of lighthearted operas, Gioachino Rossini did not restrict himself to that genre alone. As a boy of only 12 years, he was already accepting commissions to write small chamber works, including the present set of six string sonatas commissioned by the wealthy Agostino Triossi. Triossi was an accomplished amateur double bassist, a fact to which Rossini paid homage by scoring the six sonatas for a quartet made up of two violins, cello, and bass.

With the number of Vivaldi concerto recordings flooding the market, what is a starter CD-buyer to do? How can he or she make a choice? Perhaps if a reviewer has any function at all, it is to steer the prospective purchaser in the right direction. If you like period instruments, the new disc with Giorgio Sasso might be a candidate for an ideal one-CD Vivaldi choice.

After hearing I Musici perform, Arturo Toscanini remarked, "Twelve individual instrumental masters, and together the finest chamber orchestra in the world." This Italian ensemble has long attracted international attention for their emphasis on brilliance, strength of attack, and high level of discipline, beginning with their first performances of seventeenth and eighteenth century Italian music. The group was formed in March 1952 by 12 students at the Accademia di Santa Cecilia, Rome, who developed a common interest in pre-Classical music during conservatory meetings. Upon origination the ensemble was composed of six violins, two violas, two cellos, a double bass, and a harpsichord; there were three women and nine men.

In the corpus of recordings made by I Musici on behalf of Phillips, it still counts the recording of Vivaldi's Op. No. 3 - L'Estro armonico. This is not the case to deepen the artistic element of the famous chamber music ensemble. Suffice it to say that despite the contributions of the executive philology, this traditional recording remains a landmark in the discography of Vivaldi, ever actual for the executive equilibrium, for the solo contributions and for its beauty in general.

Klaus Thunemann has been the world's premiere solo bassoonist for the past three decades. His technical mastery of the instrument–he has the facilty of a violinist–is impressive in and of itself, but he brings so much more to these hard-to-find recordings of Vivaldi's elegant concerti.

A couple of the concertos included here, RV 452 and RV 446, were only discovered in the 1960's, and while there is a discussion in the notes about their provenance (they "differ slightly, in terms of style, from what is generally regarded as undoubtedly authentic Vivaldi"), they have been accepted as having come from the master's pen. In any case, Heinz Holliger and I Musici perform these small masterpieces to perfection. The allegro of RV 463 exemplifies the glorious sound produced by I Musici - big, lush and swinging - and a modern musical approach that now ironically may be somewhat out of fashion.

Visitors to Venice had borne witness to Vivaldi’s prowess as a violinist, although some found his performance more remarkable than pleasurable. He certainly explored the full possibilities of the instrument, while perfecting the newly developing form of the Italian solo concerto. He left nearly five hundred concertos. Many of these were for the violin, but there were others for a variety of solo instruments or for groups of instruments, including a score of such works for solo flute or recorder, with strings and harpsichord. He claimed to be able to compose a new work quicker than a copyist could write it out, and he clearly coupled immense facility with a remarkable capacity for variety within the confines of the three-movement form, with its faster outer movements framing a central slow movement.
