RADIO MACONDO salutes everyone about to take part in the May 1 marches to call attention to the conditions and lives of the 40 million-plus Latinos living in the United States, as well as the millions of immigrants of all nationalities. Then, we celebrate this marvelous Latin contribution to American music known as Salsa, with tracks by Jose Alberto, Los Van Van, Tito Nieves with Celia Cruz, Cheo Feliciano, and Ismael Miranda; Chino Nunez and La Sonora Carruseles--all tracks of salsa ABOUT salsa. Then, into contemporary hits with Victor Manuelle, Gilberto Santa Rosa, and Roberto Blades. And we close out this celebration with examples of son-about-son by Papi Oviedo, Sierra Maestra, and Ismael Miranda. Uplifting rhythms, and plenty of grooves
