Concert Previews

There are two quality shows amid the blooming begonias and impatiens at Longwood Gardens this weekend. Tonight, it's Tcheka, the guitarist born Manuel Lopes Andrade, who hails from the Portuguese-speaking island nation of Cape Verde, off the coast of Senegal. The former television cameraman displays a feathery voice and beautiful command of his instrument on the mellifluous

Lonji,

an album that should put him in the discussion with other Cape Verdean masters such as the sublimely soulful Cesaria Evora. On Saturday, it's Sones de Mexico, the dazzlingly diverse quintet of Chicago-based, Mexican-immigrant, folk musicians. To get an idea of all Sones can do, consider that the band's new album

Esta Tierra Es Tuya

, contains covers of Woody Guthrie, Johann Sebastian Bach and Led Zeppelin.

Talk about a comeback: A full 28 years after the release of their last studio album, the Eagles - who, in the early '70s, picked up the country-rock torch from maverick Gram Parsons and ran with it all the way to the top of the charts - returned last fall with the mega-selling

Long Road Out of Eden.

The album quickly went platinum seven times over, and earned the group - now composed of founding members Glenn Frey and Don Henley and later bandmates Joe Walsh and Timothy B. Schmit - a Grammy Award in a (not-too-surprisingly) country music category.

While the Eagles will perform tracks from the new record at their three forthcoming area shows, it's the imbedded-in-memory hits from their heyday - "Hotel California," "Best of My Love," and "Heartache Tonight" among them - that will truly get fists pumping. And a whole new generation of fans awaits the high-flying foursome, too, with the Eagles showing up in the much-anticipated music-video game Guitar Hero: On Tour.
