Poor packaging results in defective CDs
The CDs in this set are not packaged in standard jewelboxes nor even in cheap sleeves, but are mounted directly atop a printed surface. As a result, when I purchased the set from my school bookstore, I found that several of the CDs had dried flecks of ink on the data side that made it impossible to play or rip certain tracks. Beware.

Great and accurate.
I received these cds well on time, and upon discovering they were the wrong cd set the return also took place quickly.

The Standard
If you're a music student at almost any major school (I just finished my undergraduate at Indiana University, for example) you'll most likely need to take a course that uses these CD's as part of its history survey. For that purpose, this set is an excellent collection. These, with their companion Norton Anthology of Western Music, and in conjunction with Grout/Palisca's History of Western Music, make for a thorough survey of the roots and history of Western music. Both the History and the Anthology use these CD's, and make constant references to them. (At least, up until 1750, after which you'll need the second volume)

Having said that, however, i'm afraid that these CD's are limited to their intended purpose. Obviously, there would be absolutely no way to have a comprehensive collection of music and text be affordable to an average college student. As it is, the Grout, Norton, and CD's total about $200 total. However, for that cost they provide an extremely good survey of Western music. A student can follow historical developments through the music, and learn an enormous amount from these CD's. They provide a fairly good cross-section of different styles of major composers, and even a few examples of lesser known composers. One is far less likely to criticize the music of the twentieth century, for example, if one finds that Gesualdo (of the late 16th century) was writing music that was MUCH stranger than anything before the turn of the twentieth century.

For someone outside of the music school (who will most likely be required to buy these anyway), these are also an excellent (and comparatively affordable) way to survey the mainstream and less-mainstream trends in Western music. The recordings are all relatively high-quality, often using historical instruments and interpretations (something important to a student of musical history) and providing a good introduction to classical music.

For that reason, then, i recommend these to the casual listener as a good introduction to Western music. If you seek a "greatest hits" album, these are not that; go buy those Time-Life things they advertise on television. This is rather a serious collection of music from as many different styles as allowable while still maintaining some depth. The only thing that keeps the fifth star empty is the lack (by necessity, though i must admit) of a more wide-ranging selection of music. Despite that, they are still an excellent buy. The casual listener of classical music should find these to be a valuable introduction to the well known, and also the more obscure realms of early music.
