The real story of Maryland's unique community connections often begins with the smoke of an open flame, the scent of food drifting across a suburban park, and the crack of a musical instrument.
In this story, sofrito and Plena hand drums started it all.
On May 30 in Sandy Spring, that story comes alive. What began as a quiet diaspora has spent over a decade growing into a cultural powerhouse—quietly rewriting what Maryland can be.
Every grassroots movement has a turning point. For Cultura Plenera, it was a single Facebook post written by a retired U.S. Navy veteran named Angel Rivera. The prompt included a simple ask: "We will be at Centennial Park. Bring a dish."
Four musicians. A park. A few foil-wrapped casserole dishes. They did not know if anyone would show up.
150 people did.
Four months later, they tried again. 300 people showed up.
That was not just a party. It was a signal. When 150 people materialize in a park to share food, rhythm, and song, it means a gathering is long overdue. Rivera—with discipline forged over twenty-plus years in naval service—recognized the void.

Image: Angel Rivera.Throughout his military career, he built bands wherever he was stationed—Florida, Japan, and finally Maryland. But the music was still personal, meant only for playing with friends. The purpose shifted after he retired. His wife, a schoolteacher, asked his band to perform for a Hispanic Heritage Celebration. Year after year, displaced Puerto Rican parents approached him with the same question:
"Where can we listen to Plena in Maryland?"
The answer, at the time, was nowhere.
So Rivera built somewhere. He sought out mentorship from Los Pleneros de la 21 in New York City—a Grammy-nominated cultural institution that has spent over 40 years preserving roots music. By studying their operational model, a casual backyard potluck evolved into a formalized cultural powerhouse in the DMV.
When you step onto the grounds of the Sandy Spring Museum on May 30, you will hear two distinct musical lineages. They are the only indigenous Afro-Puerto Rican genres on the island. Salsa came from New York via Cuba. Merengue and Bachata came from the Dominican Republic. But Bomba and Plena? Those belong to Puerto Rico alone.
Bomba is raw, heavy, ancestral. It traces back over 300 years to enslaved Africans working sugarcane plantations. Large barrel drums drive it, but the real magic is the hierarchy: the dancer does not move to the drum. The lead drummer must instantly translate the dancer's sudden, physical improvisation into a sharp acoustic strike. The dancer leads. The drum follows. That is power.
Plena emerged later, in the early 1900s, from the urban working barrios. It represents the complex cultural melting pot of Spanish, African, and Indigenous Taíno heritages. Sung in Spanish, played on portable hand drums and a hollowed-out gourd. People call it "the newspaper of the people" because the lyrics used to spread local news—neighborhood scandals, historic fires, weddings. The crowd sings along. That is community.
Bomba demands you listen. Plena invites you to join. Together, they tell the whole story.
This is how it all started.The food at this festival is not catered. It is made by people who cook the way their families taught them. The dishes people drive hours to find made by vendors who learned to feed a crowd because this community kept showing up.
Alcapurrias. Imagine the perfect empanada or crab cake—golden brown, crunchy, shattering when you bite into it. That is an alcapurria. The outside is made from green banana and yautía (taro root). The inside is seasoned ground beef, still steaming. The magic is the contrast: the shattering exterior, the aromatic richness inside. You will eat it standing up, paper plate in hand, grease on your fingers. You will close your eyes for a second.
Pinchos. A grilled pork skewer that tastes like the best backyard barbecue you have ever been to. The marinade—adobo, a blend of garlic, oregano, and a whisper of turmeric—gives it a warm, earthy flavor. The edges are charred. The inside is juicy. You eat it with your hands, no apology.
The potluck spirit never left. It just got bigger.
Keeping a cultural organization alive requires balancing administrative work against the realities of a 40-hour work week and a long commute. Rivera manages grant writing, logistics, and social media during evening hours, backed by a dedicated collective of 24 members and an active board of directors.
A core tenet of Cultura Plenera's mission is strict: every public event must remain entirely free. No finances as a barrier. To make that work, the organization relies on a diversified funding matrix: grants from ArtsCONNECT (Mid Atlantic Arts) and the Maryland State Arts Council, institutional partnerships with the Friends of the Brunswick Library and the Sandy Spring Museum, paid performance fees from private events, and modest vendor fees.
Before securing 501(c)(3) status in 2016, the group funded community events purely through commercial performance fees. Today, the model is more stable. But the principle has not changed: remove money as an obstacle to gathering.
The cultural preservation work feeds directly into local entrepreneurship.
Rivera and his daughter, Crystal, operate the Puerto Rico Distillery in Frederick, Maryland—the only commercial producer of Pitorro (traditional sugarcane moonshine dating back to 1797) in the continental United States. The business was born directly out of a Cultura Plenera fundraiser, where supporters drove from as far as North Carolina just to buy the traditional spirit.
"Puerto Rican Born. Maryland Made."
The distillery is not the only thing growing. Cultura Plenera is, too.
Now celebrated as an economic engine, the distillery is expanding into a historic 16,000-square-foot facility in Brunswick. Later this year, the building will also house a new cultural center for Cultura Plenera.
In recognition of this seamless blend of heritage and commerce, Rivera received a Maryland Heritage Award for his achievements in both traditional music and historic distilling.
He is not just saving culture. He is building an economy around it.
Performing Plena at Upstairs at Smoketown in Brunswick.Friday, May 29 — 7:00 PM
Upstairs in Smoketown, Brunswick
A rare, intimate performance by Los Pleneros de la 21. The Spanish Harlem-based cultural institution has spent over 40 years preserving roots music, earning a Grammy nomination for their album Para Todos Ustedes. As the direct musical mentors to Cultura Plenera, their arrival in Maryland is a momentous cultural exchange. Free.
Saturday, May 30 — 12:00 PM to 6:00 PM
Sandy Spring Museum (17901 Bentley Rd, Sandy Spring, MD)
The full festival. Interactive percussion workshops. Local artisans. Food vendors serving alcapurrias and pinchos. No tickets. No gates. Just culture.
Ultimately, the true measure of this movement lives quietly beyond the official accolades, governor citations, or heritage awards. It thrives within the unshared, deeply personal stories of individuals who find an unexpected sense of warmth, healing, and absolute belonging among hundreds of strangers under a Maryland sky.
When music, food, and community converge with such uncompromising authenticity, they do more than just celebrate a culture—they expand the very definition of what makes Maryland beautiful. By folding the resilient rhythms of the island into the historic landscape of the Free State, this gathering ensures that for a few unforgettable hours, anyone can pull up an open chair, share a plate, and realize that home is not just where you are from. It is the beautiful space you build together.
Mark your calendar for two free events that could not be more different, but both deserve your attention.
On Friday, May 29 at 7:00 PM, head to Upstairs in Smoketown in Brunswick for an intimate concert by Los Pleneros de la 21. The Grammy-nominated mentors of Cultura Plenera. Forty years of preserving bomba and plena in New York. Now in Maryland for one night. Free.
On Saturday, May 30 from 12:00 PM to 6:00 PM, make your way to the Sandy Spring Museum at 17901 Bentley Rd in Sandy Spring, Maryland. This is the main event. The full Puerto Rico in Maryland Festival. Live music. Percussion workshops. Local artisans. And food—alcapurrias, pinchos, the kind of street food people drive hours to find. No tickets. No gates. Just culture. Free.
Go to one. Go to both. Just go.
