FRIDAY:

>> Rahway, New Jersey’s Eric Roberson (pictured left) is one of the most popular indie-soul singers around and got his start in D.C. during his days at Howard. Not to mention he’s written songs for industry heavyweights like Jill Scott. He’ll be with Cooly’s Hot Box alum Angela Johnson at The Birchmere. Doors at 7:30 p.m., $22.50.

>> Vinicio Capossela is an offbeat, theatrical Italian folk-pop performer into spaghetti-western soundtracks, tango, and 1950s American beat writers. He recorded his most recent album, Ovunque Proteggi (May You Protect Me Everywhere) in such locations as a cave in Sardinia, a Renaissance-era church in Sicily, and a 19th century theater. He will be performing for free at the Kennedy Center Millennium Stage at 6 p.m.

>> Local music fans should head to see No Second Troy take the main stage at the Black Cat, along with Three Stars vets The Vita Ruins and Lejeune. $10, 9 p.m.

>> Muhammad Yunus, who won the 2006 Nobel Peace Prize for his pioneering microcredit banking in Bangladesh, will be at Wesley United Methodist Church to discuss his book Creating a World Without Poverty. 7 p.m.

SATURDAY:

>> Once upon a time there was a compilation record album of D.C. bands called 30 seconds over DC: Here comes the New Wave that included Half Japanese, the Chumps and others. Now decades later, “30 Years Over DC” will feature various local rock vets including a reunited 9353, Ottley! (with Slickee Boys members), The Howling Mad (w/ Razz members), Rambling Shadows, Rustbuckit (w/ Black Market Baby members) and The New Standard at the 9:30 Club for $12.

>> Like a lot of city-dwellers, I’ve spent a fair amount time salivating at those shiny, pretty Vespas you see people riding around town, thinking they seem so practical and adorable and sporty and maybe I should just go ahead and get one! That is, until a woman I know rode up to a party this summer on her impressive, serious motorcycle. It was at that moment that I realized scooters are for bitches, and real women ride hogs. So it’ll be tough for me to stay away from the Cycle World International Motorcycle Show at the Washington Convention Center this weekend, if only to dream. Tickets are $11 per day or $20 for the whole weekend. More details here.

SUNDAY:

>> The documentary film The Gates screens in the National Gallery‘s East Building Auditorium for free at 5 p.m., with a post-screening discussion with Jeanne-Claude and Christo themselves. Check out weekly film column for a full description.
