Is it possible that a recorded performance could be too much of a good thing? Well, such an assessment probably would be unfair to a singer as gifted and in command of such astonishing technical skills as countertenor Philippe Jaroussky, so impressively exhibited on this surprising and thoroughly mesmerizing CD. While you may not have heard of this French singer, he's part of a relatively new group of performers–calling themselves Ensemble Artaserse–who have recently joined to explore their mutual interests in "early 17th-century Italian music". These songs by Benedetto Ferrari provide the perfect medium for Jaroussky's art–and it's quite formidable in both purity of tone and subtlety of expression as well as the near-inhuman technical feats he brandishes as naturally as breathing.

Gluck wrote his opera seria Ezio in 1750 for production in Prague. (In 1762, after the formal and stylistic breakthroughs of Orfeo ed Euridice, he revised the opera for a Vienna production, but it's the original version that's recorded here.) The opera has many of the characteristics of Italian late Baroque opera; it's essentially a series of arias separated by accompanied recitatives, the formula that the composer reacted against in Orfeo. It's not Gluck at his most innovative or original, but it's a fine example of opera seria, with a number of impressive arias and some very expressive recitatives, and it can make quite an impact in a performance as fine as this one.

The Stabat Mater by the Italian late baroque composer Giovanni Battista Pergolesi (1710- 1736) invariably holds the number one position in many western classical music charts. In Pergolesis own era, his composition received enormous acclaim and was frequently a source of inspiration for the many tone poets who wanted to follow in his footsteps. For this version, we brought together two wonderful vocalists who are symbiotic and complementary both in terms of personality and musical interpretation: soprano Amaryllis Dieltiens and countertenor Clint van der Linde.

Over 40 years of collaboration between Eugene Ormandy and the Philadelphia Orchestra is among the most dazzling and longest connections in the history of classical music. In this unique edition, all mono recordings from the period from 1944 to 1958 appear on 120 CDs for the Columbia label. They also reflect an important section of record history in the changing cover design. Ormandy, a master of orchestral brilliance and timbres and also appreciated as an excellent companion, created the famous "Philadelphia Sound" with his orchestra.
