Friday-Sunday  Howard University's annual homecoming celebration never disappoints when it comes to drawing musical headliners. The Yardfest hip-hop show -- which, for the first time, will charge admission of $5 -- on Friday features Big Sean, Juicy J, Bone Thugs-n-Harmony, A$AP Ferg and Gyptian at noon. The homecoming weekend's R&B sets include Erykah Badu (Friday at 10 p.m.) and Trey Songz with Brandy (Saturday at 10 p.m.) at Howard's Cramton Auditorium and Eric Benet with Lil Duval (Saturday at 7 p.m.) at the Howard Theatre. Check out our guide to the best of Howard Homecoming here.

Friday-Saturday: One of the most lauded jazz albums of last year will come to life this weekend when jazz composer and trumpeter Wadada Leo Smith performs his epic Pulitzer Prize-nominated "Ten Freedom Summers" -- a chronicle of both tragic and triumphant milestones in the civil rights movement, painted in rich jazz music -- at the Atlas Performing Arts Center. Smith and accompanying musicians will perform the ever-evolving suite over three concerts, pairing songs with photo projections evoking the civil rights era. For the Washington performance, the composer will debut additions to the cycle, including "That Sunday Morning," an ode to the victims of the 16th Street Baptist Church bombing, and another tune inspired by the March on Washington.

Friday-Sunday: Spooking the animals is usually frowned upon at the National Zoo, but for a few days each October, that changes, all for Boo at the Zoo. That's when scores of children don their Halloween costumes and take to trick-or-treating there, with treat stations set up at points throughout the park. Also on tap at the event (best for ages 4 to 12) are plenty of Halloween-themed animal events. Tickets are still available; save a little cash on the ticket fees by heading to the zoo's visitor center between 10 a.m. and 4 p.m. daily.

Friday-March 2:  It wasn't until the mid-20th century that the Latino community began to express its collective artistic identity, which makes many of the 92 works exhibited in "Our America: The Latino Presence in American Art"  reflective of the contemporary issues of civil rights, assimilation and language. Among the artists on display: Xavier Viramontes, Freddy Rodriguez, Judithe Hernandez, Sophie Rivera and Frank Romero. The exhibit opens Friday at the Smithsonian American Art Museum -- proof that it's back to normal after this month's shutdown.

Saturday: What was once just a few upstart undead lurching their way across Silver Spring terrifying people on their way to DSW has turned into a full-fledged fear parade: The Silver Spring Zombie Walk returns to downtown on Saturday. Adorn yourself in your finest fake blood, practice saying "Brainnnnsssss! Nom nom nom!" in your most frightening voice, and head to Jackie's, where would-be zombies are planning to gather at 8 p.m. The zombie walk concludes with a late showing of "Return of the Living Dead" at the AFI Silver.

Saturday: The premise of Camp Freddy is more guilty pleasure than groundbreaking: Five rock stars, including Dave Navarro (Jane's Addiction), Chris Chaney (Jane’s Addiction) and Matt Sorum (Guns N’ Roses and Velvet Revolver), are the core group, blasting out covers of Van Halen, Cheap Trick and Led Zeppelin. The trick is that the crowd never knows who the guest stars will be: Slash, Steven Tyler and Robin Zander are among the legends who’ve sat in for a song or two. All proceeds from ticket sales of Saturday's show at the 9:30 Club will benefit the Boulder Crest Retreat, a camp for wounded warriors and their families.

Sunday: The months of training are over and the runners of the 38th Marine Corps Marathon are ready to toe the starting line. But no matter how many gels a runner has packed, the best boost on race day comes from an enthusiastic crowd cheering the competitors along the 26.2-mile course. Grab a spot along the route, which begins near Arlington National Cemetery and winds through Arlington, Georgetown, Rock Creek Park, the Mall, Hains Point and Alexandria before finishing near the base of the Iwo Jima Memorial.

Sunday: Funk master/consumate party-starter George Clinton might seem like an excellent concert to kick off the weekend, but the septugenarian rocker will instead shake the walls at the Howard Theatre on Sunday night; if you're still in town after HU homecoming, or you just need a jolt to carry you through next week, make it a point to catch this concert.
