This week's lineup: Yet another searing mambo-jazz from Tito Puente, then down to Cuba for another hit from Maraca. Contemporary hits from Los Titanes, La Sonora Poncena, El Gran Combo, Marc Anthony, an all-star performance by merenguera Brenda K. Starr featuring Tito Nieves and Victor Manuelle, and India. Then, a tribute to Al Santiago (pictured), the late producer who started the first latin record label in New York, Alegre Records, and spawned an industry, featuring a rare relic from his collection. More classics from the Alegre-Fania years, with Eddie Palmieri, Cortijo y su Combo with Ismael Rivera, and Willie Colon with Hector Lavoe.
