"Los Pleneros de la 21, the premier Spanish Harlem-based performing ensemble and non-profit community organization, was founded in 1983 by Juan Gutierrez (National Endowment on the Arts' Heritage Fellow, 1996) and Marcel Reyes Arvelo. Having toured extensively both nationally and internationally for nearly three decades, Los Pleneros are considered by many as New York's preeminent Bomba and Plena ambassadors to the world, bringing Puerto Rican culture and music to Hawaii, Canada, Mexico, Cuba, Latin America, Australia, Berlin, The Kennedy Center, Carnegie Hall, the Kremlin (former Soviet Union) and countless other international cities and prominent venues. Their landmark community-based programming has created a common space for the recognition, education and practice of Puerto Rican culture and identity, having educated thousands of individuals, young and old, and inspiring dozens of perming groups and aspiring musicians." http://www.losplenerosdela21.com/ All proceeds from the event go directly to Columbia Student Medical Outreach (CoSMO), Columbia University Medical Center's oldest student-run clinic. CoSMO provides free, high-quality primary healthcare to the uninsured population of Washington Heights. CoSMO is fully run by volunteer attending physicians and students from the schools of medicine, nursing, public health, physical therapy, nutrition, and social work.
