THRILLS

Monday September 5 The Aquarian landscape: What better way is there, after all, to face the transition into fall than at a fair that is all about transitions and rejuvenation? Dance to a different drummer at the Boulder New Renaissance Festival, a weekend event ending today in Boulder's Central Park, at Broadway and Canyon Blvd. From noon until dark, open-minded folks can explore various pavilions steeped in new-age philosophy--from the Health and Wellness Area to the Women's Moon Hut, they'll encounter environmental and health alternatives, psychics, live theater, electric vehicle races, juried arts and crafts, and the Visionary Flag Perimeter Project, a collection of banners created by teams of schoolchildren. New-agers can also yuk it up during a comedy marathon featuring improv troupe the Underground or hobnob with wise older folks in the Council of Elders tent. Admission is free; call 939-8463 for information.

Tuesday September 6 Been Dan so long: There's never been a band more glossy, high-tech or complex than Steely Dan, named facetiously after a dildo in William Burroughs's Naked Lunch. The creative union of songwriters Donald Fagen and Walter Becker (responsible for tunes like "Rikki Don't Lose That Number" and "Do It Again"), Steely Dan was acidic, jazzy and musically impeccable, rooted in the bohemian Fifties while taking a true spin through the decadent Seventies. And now, the slick, ultramodern Nineties: Fagen and Becker have reunited and are touring with a big band that will drop in tonight at Fiddler's Green, 6350 Greenwood Plaza Blvd. Tickets to the 7:30 concert are $22.50 and $27.50; call 290-TIXS for yours.
