Black sand beaches, lush natural pools against mountainous backdrops, and the midnight sun: Iceland is a land like no other. In order to understand how this volcanic, otherworldly island has remained mostly untouched, it’s best to see the nation up close, and capturing Iceland’s breathtaking but alien landscape is a task for an artist who understands nature on an holistic level. Naturalist and photographer Feo Pitcairn’s “Primordial Landscapes,” the latest photography exhibition at the National Museum of Natural History, takes viewers on a spellbinding trip to a paradise of ice, water, and green hills.

EAT THIS

Cashion’s Eat Place is hosting a pop-up Rickey Bar throughout July in honor of Rickey Month. Three staff members have each created their own version of the drink, which requires bourbon or gin, lime, and soda. One of the variations uses Normandy sparkling cider and a tincture made of blackberries, hyssop, and chervil in grain alcohol and organic apple cider. Another uses fresh mint and a blueberry shrub. All the rickeys are $10 each or $12 for a sampling of all three. Cashion’s Eat Place, 1819 Columbia Road NW. (202) 797-1819. cashionseatplace.com. (Jessica Sidman)

Saturday: Among the exhibits that captured the public’s attention at the 1939 World’s Fair in New York was a time capsule, not to be opened for 5,000 years, that contained, among other things, a disposable Gillette razor, Camel cigarettes, and a creepy-looking Kewpie doll. In their 1984 film The World of Tomorrow, Tom Johnson, Lance Bird, and John Crowley combine newsreel footage, home movies, and promotional features from the festival to tell its story to audiences born after “the dawn of a new day,” as the fair was schlockily labeled.

Sunday: “Soul” is less a style of music than it is a quality. As surely as “head music” refers to cerebral stuff whose complexity is its selling point, soul music is a sound that speaks to you on an intangible level that runs even deeper than the heart. That’s why Akua Allrich, known and celebrated in D.C. (and beyond) for her jazz vocal stylings, nonetheless has a status as a “soul singer” that even the staunchest genre purists can’t question. It makes for a unique artistic vision that’s reflected on her new album, titled—what else?—Soul Singer.
