In the 1950s, the dance-band ensemble of Rafael Cortijo and Ismael Rivera performed several songs which they labelled as "bombas"; although these bore some similarities to the "sicá" style of bomba, in their rhythms and horn arrangements they also borrowed noticeably from the Cuban dance music which had long been popular in the island. Giving rise to Charanga music. As of the 1980s, bomba had declined, although it was taught, in a somewhat formalized fashion, by the Cepeda family in Santurce, San Juan, and was still actively performed informally, though with much vigor, in the Loíza towns, home to then Ayala family dynasty of bomberos. Bomba continues to survive there, and has also experienced something of a revival, being cultivated by folkloric groups such as Son Del Batey, Los Rebuleadores de San Juan, Bomba Evolución, Abrane y La Tribu and many more else where in the island. In New York City with groups such as Los Pleneros de la 21, members of La Casita de Chema, and Alma Moyo. In Chicago Buya, and Afro Caribe have kept the tradition alive and evolving. In California Bomba Liberte, Grupo Aguacero, Bombalele, La Mixta Criolla, Herencia de los Carrillo, and Los Bomberas de la Bahia are all groups that have promoted and preserved the culture. Women have also played a role in its revival, as in the case of the all-female group Yaya, Legacy Woman, Los Bomberas de la Bahia, Grupo Bambula (Originally female group) and Ausuba in Puerto Rico.
