In the early morning hours of Thursday April 17th, 2014, Puerto Rican singer, songwriter, and producer, José Luis Feliciano Vega, better known as Cheo Feliciano , died in an automobile accident. He was 78 years old.
As a singer, Cheo Feliciano was one of the most important exponents of salsa  and bolero  music. His artistic trajectory includes working with Joe Cuba , Héctor Lavoe , Celia Cruz , Rubén Blades , Eddie Palmieri , and Tite Curet Alonso , amongst other big names in popular music. He was admired not only in his native Puerto Rico, but in all of Latin America as well. In the following video  we can appreciate Cheo Feliciano's gift for salsa. Here he shares the stage with legendary Fania All-Stars  in celebration of the ensemble's 30th anniversary:
Twitter users lamented the great loss that his passing represents. They also expressed admiration towards his music:

Been listening to his music since I was little; you were my idol, your passing is very painful my Cheo Feliciano. Never see you live. Rest in peace Cheo.
Hoy sólo escucharé #Cheofeliciano

Great as singer, bolerista, sonero, an inspiration to many, a man who overcame his vices, as family to all of Puerto Rico.
Coliseo Roberto Clemente was elected as the venue for the public to say goodbye to Cheo Feliciano. This in order to accommodate as many people as possible who wished to pay their last respects:

Cartoonist Kike Estrada  [sp] also shows homage to Cheo Feliciano's memory:In 80 Grados [80 Degrees], an emotional account  [sp] is given by writer and Caribbean scholar Juan Carlos Quintero Herencia. He remembers Cheo Feliciano and how another great salsa singer, Puerto Rican Héctor Lavoe  (1946-1993), immortalized him in “El Cantante ” (video) [The Singer] as one of the greatest voices in salsa's history.
Héctor Lavoe en “El cantante” ha dejado inscritos los nombres del sabor y el plante salsero. Allí está el código para la fácil-dificultad del cantar salsero, además de que nos dejó la vara con la que el “Cantante de los cantantes” deseaba ser medido. Estos son sus verdaderos pares: “Mi saludo a Celia, Rivera, Feliciano, esos son grandes cantores. Coro: Hoy te dedico mis mejores pregones./ Ellos cantan de verdad/ siempre ponen a gozar a la gente./ Coro: Hoy te dedico mis mejores pregones/ Escuchen bien su cantar/ aprendan de los mejores.” Hasta ayer, Cheo era el único que desde el lado de acá de la grabación podía devolverle el saludo a Lavoe con su voz, en vida. Hoy, allí los verán: Héctor Lavoe, Ismael Rivera, Celia Cruz y Cheo Feliciano, cuatro titanes custodian el pabellón de los salseros muertos.
Héctor Lavoe has left the flavors of salsa and the image of the salsa singer engraved in “El Cantante”. There lies the code for the apparent simplicity of singing salsa. Furthermore, he left us the measuring rod with which the “singer of singers” desired to be measured by. These are his true equals: “My greetings to Celia, Rivera, Feliciano, those are great singers. Chorus: Today I dedicate to you my best songs/ They really sing/ They always make the people have fun/ Chorus: Today I dedicate to you my best songs/ Listen carefully to their singing/Learn from the best.” Up until yesterday, Cheo was the the only one on this side of the recording that could return Lavoe's greeting with his voice in life. Today, you will see them there: Héctor Lavoe, Ismael Rivera, Celia Cruz, and Cheo Feliciano, four titans watching over the pavilion of the deceased salsa singers.
Cheo Feliciano was also admired in the United States, particularly in the Puerto Rican diaspora, such as this mural in the Bronx, New York shows:
