EMI's three-disc compilation, Best Adagios 50, is divided into three categories, which may determine its appeal and usefulness to some listeners. Disc 1 is devoted to slow movements taken mostly from Baroque works, including the famous "Canon" by Johann Pachelbel and the spurious "Albinoni Adagio" by Remo Giazotto, along with relaxing music by J.S. Bach, Antonio Vivaldi, and George Frederick Handel; pieces by other later composers, such as Franz Joseph Haydn, Giovanni Battista Pergolesi, and Wolfgang Amadeus Mozart; then closing with music by the 20th century's Arvo Pärt and John Tavener. The selections of Disc 2 are exclusively by Mozart, drawing on quiet movements from his most popular concertos, symphonies, serenades, and other favorites. French Adagios are the topic of Disc 3, and the periods covered are late Romantic and early modern, featuring music by Camille Saint-Saëns, Claude Debussy, Gabriel Fauré, Francis Poulenc, Erik Satie, and Maurice Ravel. Even with the program broken down into these manageable groupings, one still might like one part of the set more than the others, or find that the plan is a bit arbitrary for devoting so much space to Mozart, who is already the subject of another EMI release, Best Mozart 50. But this arrangement of pieces at least has some clarity going for it, unlike other Adagios albums that are randomly laid out, and it's likely that many beginners in classical music will find the package fairly helpful for exploring. As with all such samplers, listeners should regard it as a good starting point, but move on to hear other recordings of full works by these composers.
