Buitrago was an anomaly amongst the coastal residents ā blonde, fair skinned, tall, neatly coiffed, tie with a perfect knot, and a ''triumphant smile'' that accentuated his prominent chin and his pronounced ears that gave away his ''paisa'' descent (his father Guillermo Buitrago MuƱoz was from the ''paisa'' region of Antioquia, whose capital city is MedelliĆn).
There MuƱoz married Teresa HenrĆquez and they had 7 children, 5 of which would die before turning 30, amongst them Guillermo, who would die at 29 precisely in the moment that he was about to sign a big contract that was going to launch his career internationally.
At 18, Buitrago was already working as an in-house guitarist on a program called La hora infantil on the radio station Ecos del Córdoba, on which children from all the local towns would sing, competing for a prize.
Buitrago started visiting radio stations to play his music, and finally had a stroke of luck at Radio Magdalena in the city of Santa Marta, where he would gain sufficient experience for his next career step in the coastal city of Barranquilla.
Buitrago since his adolescence had sought out business to record commercial jingles.
On numerous occasions Buitrago explored various opportunities to make songs to promote products or brands.
Amongst numerous brand names, he recorded jingles for Ginger Ale and Cerveza Ćguila.
Perhaps the most famous was "El ron motilón", which promoted a rum from the province of Santander, and the long-running Colombian Christmas classic "El ron de vinola", which promoted a type of sugar cane juice that was said to have similarities to wine.
7 or 8 radio shows later, along with a successful jingle ''El Negro Mendo'' that he recorded for a furniture and mattress factory, convinced the station directors to give him more air time during prime time, ultimately giving him 3 shows weekly.
By 1947 Buitrago was basically living in Barranquilla.
Emisoras Unidas, realizing the growing success of Buitrago's music, contracted Julio Bovea, who had just split from Buitrago and had formed his own band to take on an air slot that would compete directly with Buitrago's programming.
Pressed to find replacements, Buitrago contacted two musicians he had played with in years prior.
With this new group, he would go on to record the majority of his hits, all of which are still known today.
Guillermo Buitrago y sus muchachos, his band, had Ćngel Fontanilla on lead guitar, Buitrago on rhythm guitar and lead singer, and Carlos "stumpy" Rubio on guacharaca (Rubio was missing part of his left forearm).
What came next was fame and success.
Aside from radio, private parties, local fairs, serenades, by 1947 ToƱo Fuentes, founder of Discos Fuentes in MedellĆn and pioneer of the LP industry in Colombia, arrived in Barranquilla looking for Buitrago's band to take them to make a recording at his studio in Cartagena.
Elsewhere, Odeón Records of Argentina had also contacted Buitrago, producing some recording that had won a strong following nationally, so much that plans were put in motion to have Buitrago and his band tour the south of the South America.
2 successful years later, Guillermo Buitrago woke up on a day in January 1949, sick and short on sleep.
At first he suspected too many performances had him fatigued, but as the weeks passed by, he started realizing he had an illness that was threatening to become critical.
Locals claimed he had a weakened voice and that his ''young handsome face looked like a specter with burning dark circles around his eyes''.
Guillermo Buitrago died on 19 April 1949 at the age of 29 years.
The exact reason of his death remains a mystery.
and there is no shortage of rumors and suspicions surrounding the young singer's demise.
