1960s supergroup Crosby, Stills and Nash still matters.

David Crosby is 73; Stephen Stills, 70; and Graham Nash, 73. Age, however, wont be a hindrance, and could even be an advantage, when the legendary folk-rock trio collectively dubbed CSN performs Monday night, March 16, at Smart Araneta Coliseum.

Many of Manilas baby-boomer generation that spent its teenage years listening to CSN are expected to show up at the Big Dome.

But something makes this concert particularly interesting to the rest of us, including those too young to know about Woodstock, the hippie lifestyle, and the social tumult of the 1960s and 70s.

CSN is known for its intricate three-part vocal harmony style-which stood out among its peers when the singer-songwriter phenomenon was on the rise in the late 60s.

Its 1969 debut album, "Crosby, Stills and Nash," showcased that style elegantly on the very first track, "Suite: Judy Blue Eyes," consisting of four sections whose narrative documents a romantic breakup (Stills and his then girlfriend, singer Judy Collins).

"Suite-" attained the aspirations of music as art, with elements of classical and poetry wonderfully fusing in the three-part vocal harmony (Stills singing low, Crosby the middle part, and Nash the high notes).

That became the standard in other CSN tracks ("Marrakesh Express," "Wooden Ships," "Helplessly Hoping," "Long Time Gone," "Teach Your Children," "Our House," "Just A Song Before I Go," "Wasted on the Way")-songs that didnt just entertain but also told the story of young people who believed in different ways of loving and living, especially supporting activism and denouncing war.

Too bad that CSNs sometime cohort, Neil Young (the "Y" in CSNY), is not part of this concert; nonetheless it would be a joy to see the three who have come to personify survivors of sometimes destructive lifestyles and the ravages of time.
