Johann Sebastian Bach was a German composer and musician of the late Baroque period. He is known for his orchestral music such as the Brandenburg Concertos; instrumental compositions such as the Cello Suites; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier; organ works such as the Schubler Chorales and the Toccata and Fugue in D minor; and vocal music such as the St Matthew Passion and the Mass in B minor. Since the 19th-century Bach revival he has been generally regarded as one of the greatest composers in the history of Western music.

Classic Yo-Yo is a greatest-hits collection for the famous Yo-Yo Ma, something he's fully entitled to after two decades of runaway success. It's "Classic Yo-Yo" in the sense that it presents well-loved and presumably durable selections from a variety of Yo-Yo Ma albums, not because it inclines toward Ma's straight-ahead classical recordings. In fact the division between classical and crossover pieces on the disc is about 50/50, and they tend to alternate. The transition from Bach to Astor Piazzolla works OK, but that from Appalachian Journey mastermind Edgar Meyer to Brahms might be a bit jarring. A greatest-hits album is a tough item for Ma because his recordings are so different from one another and involve such a variety of other musicians. As Ma himself says in an interview included in the liner material, "Collaboration is the best part of what I do, it's what I enjoy most about being a musician".

It was only a matter of time before the remarkable Yo-Yo Ma went along with the tide and dipped his talent into the so-called authentic instrument movement. On this recital, abetted by Ton Koopman–one of the most respected names in early-music practice–Ma plays Bach and Boccherini. The Bach are all transcriptions and very fine ones, indeed–the alto aria "Erbarme Dich" from the St. Matthew Passion; the equally famous "Air on a G String" from the Third Orchestral Suite; Jesu, Joy of Man's Desiring; and six others, most less well-known. These are followed by two fascinating cello concertos by Boccherini, made all the more interesting by Koopman's cadenzas, which are pretty outrageous. Throughout, Ma's stunning virtuosity is matched by his taste and musicality. The Amsterdam Baroque Orchestra plays handsomely, and the recorded sound is warm and full. "Authentic" or not, this is mighty fine playing, and wait till you hear those cadenzas.

On 10th December, 1553, at one of the highpoints in the Golden Age of Spanish music, there appeared in Rome the TRATTADO DE GLOSAS SOBRE CLAUSULAS Y OTROS GENEROS DE PUNTOS EN LA MUSICA DE VIOLONES NUEVAMENTE PUESTOS EN LUZ by Diego Ortiz, who was also known under the name “el Toledano”. An inevitable reference point for the study of instrumental performance practice in the 16th century, this work is of exceptional interest, both for its purely historical significance and for its artistic value, since it contains the finest examples of the known repertoire for viola da gamba (vihuela de arco or violone) and harpsichord in the Renaissance period.

Couperin is too easily seen as the tender, graceful and somewhat melancholy composer, whose soft-toned palette was the same as that which served the brush of Watteau. There was another Couperin who was a master of humour and whose claws were sharp. And yet another who was a musician involved in the aesthetic battles of this time and in the avant-garde.
