Wednesday 9

If you think you can tolerate a two-hour severance from reality, those two preserves of fantasy–fashion and the movies–converge this evening at Charles A. Stevens’s Cinema Chicago fall fashion show, 5:30-7:30 at the Palmer House. The $15 ticket covers wine and hors d’oeuvres, a store discount check, and a chance to win the grand prize: a day as an extra in a Chicago movie or TV production and a year’s worth of movie tickets. 630-1500, ext. 2858, for tickets.

Thursday 10

Basically Bach attempts to perform baroque music in a “historically informed manner,” that is, trying to stay true to the intentions of the composer by using instruments and performance practices of the period: baroque brasses without valves, stringed instruments strung with gut as opposed to steel or steel-wound gut, producing a sweeter, softer sound, and winds that are made of wood and have fewer keys than modern instruments. According to them, lying on the couch with a good Brandenburg Concerto is just as effective as psychotherapy and a lot less expensive. Various soloists will join Basically Bach’s 25-member chorus for their season opener, Bach’s Mass in B Minor, 8 tonight and Saturday at the First Congregational Church, Hinman and Grove in Evanston. Reserved seats are $20, $16 for general admission. Performances also take place 8 PM Friday at the Cathedral of Saint James, 65 E. Huron, and 7:30 PM Sunday at the First United Church, 848 Lake St. in Oak Park. For info or reservations call 508-0635.

“Each year, more than 40,000 square miles of tropical forest are destroyed–an area about the size of West Virginia,” says Thomas Antonio of the Chicago Botanic Garden. But you can down some tropical refreshments and save a tree at the same time at the Botanic Garden’s benefit to aid tropical forests tonight. Afterward the Field Museum’s William Burger will give a presentation, “Where Clouds and Mountains Collide: The Magnificent Forests of Costa Rica,” at the garden’s education center. 7:30-9:30, on Lake Cook Road east of Edens. Minimum donation is $20; 835-5440 for information.

Fans of the soaps have long realized medicine’s innate drama.
