LIGHTS OUT: Celebrate Earth Hour tonight in grand style. The Trump International Hotel & Tower will extinguish all of the lights in the front drive, lobby and top tower of the property. Guests can enjoy a complimentary "Firefly" cocktail, made with Hendrick's gin, Moscato d'Asti, tonic and cherries soaked in kirsch, which emits a light glow when blended, in the hotel's elegant candlelit lobby. 8:30-9:30PM, free.
CANADIAN CLUB: See Toronto's Enter the Haggis, a band with influences as diverse as rock, folk, traditional Celtic music, bluegrass and even Latin accents, tonight at FitzGerald's in Berwyn. The band's brainy, high-energy shows are legendary. 9PM, $12-$15.
