Music both old and new, but all of it inspired by the timeless modal harmony of medieval and Mediterranean cultures: this is the subject of John Williams's brilliant guitar disc for Sony, which also features his debut as a composer. The main work is his own "Aeolian Suite" for guitar and chamber orchestra, based on both original and 14th-century tunes (one of which, the "Saltarello," appeared on early-music pioneer David Munrow's disc called Instruments of the Middle Ages). The suite is a lovely piece of writing, deftly composed, and neither tacky nor pretentious. It's paired with an inspired assortment of spiritually related but diverse arrangements and original pieces by Satie, Theodorakis, Domeniconi, and an emotionally intense four-movement work called "Stélé," by Australian composer Phillip Houghton. Naturally, Williams performs each piece expertly, but most important, he makes his instrument sing, and that's just what the music demands. Simply super.
