A Puro Dolor

"A Puro Dolor" is a song recorded by Puerto Rican band Son by Four. It was written by Omar Alfanno and released as the first single of the second studio album of the band in 2000. Two versions of the track were produced by Oscar Llord for the album; one as a salsa and the other as a ballad. The ballad version was arranged by Alejandro Jaén.

The song reached number-one on Billboard Top Latin Songs chart, and became the longest running chart topper of its history, spending 20 weeks at the top; this record was broken five years later by Colombian singer Shakira with "La Tortura" which spent 25 weeks at number-one. "A Puro Dolor" also reached the Billboard 100; this led to the recording of an English-language version of the track "Purest of Pain", which was also charted in the United States.

The composition also met with critical acclaim receiving the Lo Nuestro Award, the Billboard Music Award and a Latin Grammy Award nomination. In 2009, "A Puro Dolor" was named the best-performing Latin single of the 2000s decade in the United States. Two music videos were made for the ballad and the English versions. The record was covered by Mexican group Dinora y la Juventud and Brazilian boy band KLB both of which received radio airplay.

Background and composition
In 1998, Son by Four released their first album, Prepárense. The success of the singles "Nada" and "No Hay Razón", distributed in Puerto Rico by the independent label RJO, captured the attention of the Sony Music CEO Oscar Llord, who made an agreement with RJO to re-release the album and start the recording sessions of the next album. Llord was the brain child behind the ballad version, which was recorded at his own Extreme Studios in Miami, FL, which was the version that went on to #1. The first single taken from the following album was "A Puro Dolor", written and arranged by Panamanian record producer Omar Alfanno, with a ballad version arranged by Alejandro Jaén. Alfanno, well known for his work with salsa recording singers Marc Anthony, Víctor Manuelle, Jerry Rivera and Gilberto Santa Rosa was in charge of the album production. Alfanno declared that he wrote the song in ten minutes, and that after the success of the track, he analyzed the composition, since he did not understand how "A Puro Dolor" became that popular. He named it "the Cinderella of all his songs." After its success in the Latin market, Oscar Llord then engineered an English version of the song “Purest of Pain”, which went on to become a Billboard Top 40 hit, and performed alongside N’Sync at the 2001 Latin Grammy Awards.

Critical reception
The song was released in 2000. It became very successful with the ballad and tropical and salsa versions setting an airplay record for a Latin single with 23.4 million impressions in those countries. The reaction to the song was intense, and Son by Four was asked to record an English-language version of the track. This version, titled "Purest of Pain", was serviced to English-speaking radio stations in May 2001. The success of the song took by surprise the leader of the band, Ángel López, who told Billboard magazine: "When they told us we were going to be signed by Columbia for the single, we flipped." A ranchera version was also recorded for the Regional Mexican audience. About the song, López also declared that "has something everybody can relate to. We're adults, we've been all through that [rejection]. The way the song reaches out to people is outstanding." In his album review for AllMusic, Evan C. Gutierrez declared that "A Puro Dolor" set "an impossibly high standard for the rest of the playlist."

Son by Four received seven Billboard Latin Music Award nominations in 2001 for "Hot Latin Track of the Year", "Pop Track of the Year" and "Tropical/Salsa Track of the Year" ("A Puro Dolor"); "Tropical/Salsa Album of the Year, New Artist" and "Tropical/Salsa Album of the Year, Group" (Son by Four); and "Billboard Latin 50 Artist of the Year" and "Hot Latin Track Artist of the Year". With further nominations for Alfanno as "Songwriter of the Year" and Jaén for "Producer of the Year". Son by Four won all the awards, and Alfanno won the award for the writing of the song.

At the Lo Nuestro Awards of 2001, the group earned six awards; among them "Pop Song of the Year" and "Tropical Song of the Year". Alfanno also received a Latin Grammy Award nomination for the Best Tropical Song, which it lost to "El Niágara en Bicicleta" by Juan Luis Guerra. "A Puro Dolor" was given three Billboard Music Award in 2000 for Latin Track of the Year, Latin Pop Track of the Year, and Tropical/Salsa Track of the Year. At the 2001 ASCAP Latin Music Awards, Alfanno was awarded "Song of the Year" and "Pop/Balada Song of the Year" for his composition of the song and was named Songwriter of the Year. In 2015, "A Puro Dolor" ranked number 35 on Billboard's Best Latin Songs of All Time.

They also did a concert with the R&B trio Destiny's Child, and were presented in the 1st Latin Grammy Awards along with the boy band NSYNC, performing the medley "A Puro Dolor"/"Purest of Pain" with "This I Promise You"/"Yo Te Voy a Amar". The song was featured in the Mexican telenovela Frente al Espejo, broadcast by Televisa. that year, it served as an opening theme for yet another telenovela "mis 3 hermanas from Venezuela. In 2000, due to the success of the track in the American market, they were asked to perform on The Tonight Show hosted by Jay Leno. The salsa version of the song was included on their greatest hits album Salsa Hits (2001) and Lo Esencial (2008) and on the compilation album Salsahits 2001 (2000).

Two music videos were made for the song; the first one for the ballad version, and the other for the English version. The ballad version was directed by Felipe Niño. In the video, the group is shown performing the song along with an orchestra behind them. It is filmed on a stage where shows López singing his verses, while the others members of the group, follow up with the chorus. At the end of the video the people of the orchestra starts to applaud when the group ends to sing. In the English version of the video, the plot is completely different. The video starts in a cloudy afternoon after a storm, where the group is situated in a white room. It shows López singing in a ladder when it later starts to fill with water. At the last part of the video, it shows Son by Four singing out of the house after the storm has ended.
