The title of this set is Complete Symphonies, but this is not to be. In the Gerard catalog, there are 29 symphonies, but G516, Symphony Nr. 22, has been lost; thus, the 28 symphonies. However, cpo includes G491 calling it a symphony while in the notes refers to it correctly as a Sinfonia concertante. For some reason G521, Symphony Nr.27 is not included in this set. It is available however on Capriccio 10458 with Erxleben conducting (numbered 19 in the pre-Gerard catalog). To cpo's credit this work only exists as a one movement fragment and is also called an Overture, but then in the 18th century often the word overture was synonymous with symphony.
The performances here are excellent throughout. The notes are excellent other than failing to mention G521 or G516. Being able to listen to all the Boccherini symphonies gives a superb picture of the development of a composer who was somewhat isolated and restricted in performance opportunities. There are numerous recordings of the Op. 12 set (G503-508), but this collection provides the opportunity to listen to the symphonic development of Boccherini. There are sufficient aspects of these symphonies to make them enjoyable and entertaining. have unique characteristics, extended use of solo instruments, harmonic diversity, form alterations, and contrasting movements within a symphony.
For a listener who wants to work through the complete picture, this is a highly recommended set. For the listener who wants to sample the highlights,there are other good recordings available.
