The talented female a cappella quartet Anonymous 4 is anything but anonymous. The New York City-based quartet is known for its virtuosic vocal blend of medieval music from the year 1000, American folk songs, and even music of the 12th-century abbess and mystic Hildegard of Bingen. They've performed around the world and are regulars at several major international festivals throughout Europe, Asia, the Middle East and North America. The group consists of Susan Hellauer, Ruth Cunningham, Jacqueline Horner-Kwiatek and Marsha Genesky, and together, they've made an impressive 19 best-selling recordings. They will be performing at 7:30 p.m. at the Kennedy Center (2700 F St. NW) in the Terrace Theater. Their performance, "Love Fail," is a collaboration with Pulitzer Prize-winning composer David Lang. Tickets are $38 at kennedy-center.org.


The Red Ribbon Dine-Out Night is upon us, and if you didn't go last year, then here's your chance. Kimpton Hotel's fine-dining restaurant, Jackson 20 (480 King St., Alexandria), is hosting a lavish, Southern-inspired dinner to help raise money for the Northern Virginia AIDS Ministry, or NOVAM, an organization that provides education and services for those affected by HIV/AIDS. Chef Brian McPherson's pre-fix menu includes a half-rack of BBQ pork ribs with apple cider coleslaw and Virginia cheddar mac & cheese. Top it off with grasshopper pie and a signature Red Ribbon cocktail made with Pama Pomegranate Liquor, Lillet Blanc and fresh lime juice. The dinner costs $35 and starts at 5 p.m. You'll be added into a Red Ribbon raffle that could lead to some great prizes. For more information, go to novam.org.
