Fleetwood Mac deliver the old tunes here with note-perfect skill and obvious enthusiasm. The voices are a bit weathered, but few bands harmonize as beautifully. Nicks avoids the high notes on "Landslide," but a few decades' perspective adds a world-weary dimension to lines like "Can I face the seasons of my life?/I don't know." The Mac don't tinker much with the hits, although Christine McVie's "Everywhere" has a salsafied, everybody-onto-the-lido-deck feel, and Buckingham turns in a stark, flamenco-laced "Big Love."

The new songs blend in seamlessly, sounding at once like familiar old pals. "Bleed to Love Her," via Buckingham, is a folky, gentle, early-Sunday-morn tune, while his jaunty "My Little Demon" sounds like "I Don't Want to Know" on speed. The best track is "Silver Springs," a lovelorn song that Nicks wrote 20 years ago. She's at her contemplative-gypsy best, and it's an instant Mac classic. Her new "Sweet Girl" is an Allman-esque Southern-rock ramble. Finally, there's Christine McVie's "Temporary One," a bouncy, we'll meet-again ditty. "The sea that divides us is a temporary one," she sings, "and the bridge will bring us back together." Sounds like the theme song for a certain inveterate group.
