Carlos Almagro, born Santiago La Camera on June 29, 1929, in the neighborhood of Flores, Buenos Aires, Argentina, was a notable tango singer. He emerged in the late 1940s, participating in vocal contests organized by neighborhood clubs and tango venues. In early 1953, he joined violinist Hugo Baralis's orchestra at LR3 Radio Belgrano, alongside vocalist Juan Carlos Rolón. After the orchestra disbanded in 1954 due to Baralis's tour to Japan with Juan Canaro, Almagro was recruited by Miguel Caló as a substitute for Roberto Arrieta, performing with renowned singer Alberto Podestá.

Almagro made his recording debut in October 1954 with the tango "Los cosos de al lao" and recorded "Por unos ojos negros" and Miguel Nijensohn’s waltz "La barquilla" with Trío Los Halcones in May 1955. His last recording with Caló's orchestra was "Bien jaileife" in June 1955. He briefly joined Florindo Sassone's orchestra for carnival balls and later performed with Ángel Domínguez at LR4 Radio Splendid, recording "Suerte loca" and "Porque te quiero así."

Almagro's career peaked with Rodolfo Biagi's orchestra, where he shared vocals with Hugo Duval. He participated in Biagi's last recording in 1962, featuring tangos like “Si no estuvieras tú” and “Palermo.” After the Biagi orchestra disbanded, he embarked on a solo career, recording Milongas Reas with Cuarteto Puro Tango in 1966 under the Magenta label. Despite the challenges of a shrinking market for tango music in the mid-1950s, Almagro's unique voice and intonation left a lasting impression in the tango community.
