I knew Celia Cruz by her TV shorts. She was like any Latin showgirl in Club Tropicana. She was the "Rita Moreno" of salsa singing because I believe that even when the music trends faded away from mambo (from her experience with her past conjunto, La Sonora Matancera) to rap and techno-driven stuff. Celia adjusted to new music trends, combining salsa with merengue, cumbia, and other Latin and non-Latin forms.
One of the things I remember about Celia was not just her famous shout "Azucarrrrrrr!"--but also the song "Timbala Timbala" song. The song reminiscences the first rumbas during the 1950s and 1960s, when fast mambos (like "Para Los Rumberos") were common. It was a very fast salsa and I was trying so hard to keep the beat with my big salsa steps to that music.
I was watching funeral coverage on the Telemundo network, and the pre-mass funeral procession that led to the church. The hearse car was decorated with flowers as the procession crowed threw flowers in respect to the loss of this great salsa-singing lady.
