Chicago:

Anniversaries clocking in at 25 years traditionally require gifts of silver. The Plank Road Folk Music Society isn't asking for any silver tea sets, platters or fine, delicate necklaces for its 25th anniversary celebration. All the music enthusiasts ask is that you attend the 25th Anniversary Party. And who can resist a party, especially when there's music involved? The daylong event kicks off with a few hours of jamming and sing-arounds; then there's a break for dinner and the night concludes with a concert by Mark Dvorak, above. Fans of folk and bluegrass music shouldn't miss this soiree. 2 to 9 p.m. Saturday, First Church of Lombard, 220 S. Main St., Lombard; free for PRFMS members, $10 for nonmembers; 630-325-7764 or plankroad.org
