Has anyone considered that Facebook can be torturous for those of us too busy or too shy to make time to hang out with our legions of virtual friends? Facebook fatigue has one potential cure in JBar’s Addiction Thursday party tonight, which “honors” those obsessed with Facebook. Partygoers can even drink “The Tag” and “The Poke Me” for $6 each and play Facebook trivia. What these people look like in real life is the most pressing question.

Here are five things to do.

MUSIC - Vic Chesnutt
Chesnutt’s particular genius is in making every detail palpable, every emotion inevitable. Tonight, he is backed by what should prove a fascinating band: Fugazi’s Guy Picciotto on guitar and members of Godspeed You! Black Emperor. Lincoln Hall. 9pm; advance $18, day of show $20.

THEATER - Calls to Blood
Knowing that the twist that fuels James Asmus’s play, about a seemingly perfect marriage that goes downhill faster than a speed skier, is purportedly based on a real case makes us want to crawl into a hole and never come out again. That the play is both gut-wrenchingly tragic and very, very funny is a mark of the New Colony’s unique outlook. The New Colony at Royal George Theatre, 8pm, $25, seniors $20, students $15.

SHOPPING & STYLE - Manicure and Martini
Nothing goes with a manicure quite like a cocktail. Seven area spas gather to give weary patrons the royal (nail) treatment. Tickets include manis, Champagne, finger foods, one complimentary martini, a chocolate tasting, as well as a head and neck massage. Reservations are required. The Drake Hotel, 140 E Walton Pl (312-787-2200, thedrakehotel.com). El: Red to Chicago. Bus: 145, 146, 147, 151. Thu 5, 5–8pm. $55, advance $45.

NIGHTLIFE - 2020 Soundsystem
The brainchild of 2020 Vision frontman Ralph Lawson, 2020 Soundsystem is a DJ-meets-live act featuring Lawson and labelmates Dubble D and Argentine duo Silver City. Fed up with the typical DJ set and drab laptop live show, Lawson formed the group to enhance his performances and has since headed into the studio with them, releasing two albums that have both been met with generally warm reviews. It performs as part of Vision Nightclub’s new Art of Sound, an ongoing multimedia and events series that showcases progressive electronic music talent as well as live painting and visual projections. Vision. 10pm, $20.

FILM - The Hurt Locker
As part of your early preparation for this year’s Oscars race, check out The Hurt Locker. If this doesn’t get nominations for Best Picture and Best Director, we’ll eat an army-issue helmet. Gene Siskel Film Center, 164 N State St at Randolph St (312-846-2600). El: Brown, Green, Orange, Pink, Purple (rush hrs) to State/Lake; Red to Lake; Blue to Clark/Lake. 8:15pm. $9, students $7, members $5.
