The salsa and bolero singer Cheo Feliciano has died at the age of 78. He was killed early this morning in a car crash in San Juan, Puerto Rico. Born in Puerto Rico, Feliciano moved to New York City and started out as a percussionist before going on to sing with the Joe Cuba Sextet and, later, the Eddie Palmieri Orchestra. Last year, Feliciano announced he had been diagnosed with a treatable form of cancer.
