In the past two years, Fleetwood Mac has breathed some much-needed life into commercial pop music. Heart and Walter Egan both benefited from the Mac's example and combined original music with commercial appeal to get onto tight radio playlists. Sunday night at the Capital Centre, Heart proved to be more commercial, but Egan proved to be more original.

Heart's Ann and Nancy Wilson learned from Fleetwood Mac that two women singer-songwriters could lead a band rather than merely front it.Sunday night Ann Wilson marched and strutted the stage with possibly unparalled sexual arrogance.

On old songs like "Magic Man" and new ones like "Straight On for You," her voice maintained a bite of even the highest pitch. Unfortunately, her songwriting goes for the easiest emotional effects and inevitably repeats itself.

Walter Egan has learned a more valuable lesson from Fleetwood Mac: how to combine Beach Boys harmonies with a hard blues back-beat. On his hit single, "Magnet and Steel," he brought the call-and-response vocal hook to a new climax. He expanded the double entendres of the flip side, "Tunnel of Love," into a grand piece of theater worthy of the Rolling Stones. And he sang "Sister of the Moon," an unrecorded song by his former producer Stevie Nicks, with the same mystic flair of her "Rhiannon."
