Everyone loves a good surprise party. What’s better than an unexpected night of fun with friends? How about supporting an importance local arts organization in the process? Friday’s Secret ArtWorks event offers an exciting twist on fundraisers as each attendee will walk away with a piece of original artwork. The catch: guests will not know who created their work until it's been purchased. More than 800 small-scale pieces have been donated by more than 300 locally-, nationally- and internationally-renown artists. Guests were invited to preview the offerings online, but the secret artists will not be revealed until tonight. Ticket sales are now over, but tonight’s attendees will enjoy cocktails, hors d’oeuvres and a mysterious night of art at The Center downtown, all to benefit ArtWorks. The Cincinnati Symphony Orchestra concludes its community concert series “One City, One Symphony” this weekend with the well-loved classic, Beethoven’s Symphony No. 9. Music Director Designate Louis Langrée conducts the performance; these will be his final shows with the CSO before starting his role as music director for the 2013-2014 season. Joining the CSO, Langrée and the May Festival Chorus for the concerts Saturday and Sunday at Music Hall. Go here for tickets. If you thought this cold weather meant you had to retire your gold lamé hot pants, dry your tears and pull those bad boys out, because OTR Skate is back! Channel your inner roller disco king/queen and roll over to the OTR Rec Center Friday from 8-11 p.m. Five bucks gets you admission and skate rental, complimentary pizza from Cincy By The Slice, free gaming from Wii to air hockey, raffle prizes and music from DJ Positronic, The Yugos and Indigo Wild. Saturday is all about the little guy as local businesses around the Tri-state take part in Cincinnati Unchained. Get a head start on your holiday shopping (or, if you’re like me, take advantage of sales for your own damn self) and visit independent businesses  in an effort to keep your money in the local economy — where it goes much further than when you drop your cash at a big box chain store. Participating Cincinnati Unchained shops offer discounts and free goodies to thank shoppers for supporting local businesses — find a full list here. Another way to get in on the conscientious gifting trend is giving handmade presents this holiday. Did the Holly Hobbie gene skip over you? No worries. The Crafty Supermarket Holiday Show takes over the Clifton Cultural Arts Center Saturday. This isn’t your grandma’s church basement craft show — expect handmade books, cool local artwork, quirky jewelry, textiles, posters, clothing and many more hand-crafted gifts everyone can appreciate. Plenty of vendors will be on-hand to fuel your shopping in addition to a DJ, craft demos and — as usual — awesome swag bags for the first 100 shoppers. The party runs 11 a.m.-6 p.m. Saturday. Comedian Erik Griffin performs at Funny Bone on the Levee Friday-Sunday. Workaholics fans know him best as TelAmeriCorp's Montez Walker, a competitive salesman who has a very healthy sexual relationship with his wife. Here’s a sample of one of Griffin’s finest Montez moments: Check out our calendar for more art openings, theater shows, concerts and other events happening this weekend and beyond.
