A fierce advocate of South East Asian culture, Azarcon, who was a prominent fixture on magazine covers during the 90's and 2000's is partially credited (along with Karl Roy, MMA fighter Brandon Vera) for the popular resurgence of the Austro-Polynesian/Indo-Malay script Baybayin in modern Filipino culture.
Azarcon first started playing bass during the early 90s with punk funk rock band, Bazurak. They covered songs from Sex Pistols, Red Hot Chili Peppers, and the Ramones. The members included Junji Lerma, guitar player for Radioactive Sago Project; Richard Recto on vocals; Paolo Lerma on drums; J-John Valencia on guitars; and Mark Escueta on drums.
In 1998, Azarcon started his apprenticeship under Sammy Asuncion, guitar player of Pinoy funk-reggae-rock band Spy and ethnic rock group Pinikpikan, a group renowned for reinventing musical pieces using indigenous tribal instruments. Azarcon eventually joined Pinikpikan. Notable members include Grace Nono, Rene "Chong" Tengasantos and Bob Aves. Azarcon under the moniker "Elqpal", fit well with the band's ethno-tribal rhythms.
In 2000, the band released their album Atas on the Tropical Records label, a subsidiary of A&M Records. The recording won the Philippine's 2001 Katha Music Award for Album of the Year, Best World Song, and Best Performance for "Kalipay". Other standout tracks on the album include "Aumoon", "Salidumay", and "Singkilan".
In 2001, Azarcon departed from Rivermaya after a 7-year stint with the band since its inception in 1994. He eventually went back to the band after 15-years.
The band Kapatid (lit. English: sibling) came together through an informal gathering of friends with diverse musical talents in other bands. The original lineup included Karl Roy of Advent Call and P.O.T.; Marinito "J-hoon" Balbuena of Kjwan; Ira Cruz previously of Passage; Azarcon; and Chico Molina.
In 2002, the band went on to release their debut album "Edsa 524". The album contains the singles "Pagbabalik Ng Kwago", "I like it like this", and "Visions". The band split apart rather quickly, with a couple of members leaving for other bands under less than amicable circumstances. Roy later stated of the breakup, "There was lots of talk about brotherhood and respect and the joy of playing music together. Unfortunately, things didn't turn that way. The band split apart rather quickly, as a couple of members left for another band, under less than amicable circumstances. First, guitarist Ira Cruz left, and then Azarcon followed, and the two eventually hooked up with former Rivermaya bandmate Francisco "Bamboo" Mañalac."
In 2003, after living in Los Angeles following the Rivermaya tour in America, Mañalac returned to the Philippines. Azarcon introduced Mañalac to Cruz and Vic Mercado (drums) and together, they formed a band called Bamboo which is named after the grass.
In January 2011, News had been circulating that Bamboo has allegedly disbanded. DJ KC Montero of Wave 89.1 confirmed the breakup on Wave's The KC Show and via Twitter. Montero clarified that all the members of the band "have decided to move on," and that he does not know why they called it quits. The group has not released an official statement on the issue, according to ABS-CBNNews.com.
Bamboo's lead vocalist Bamboo Mañalac finally confirmed the breakup of his band in an official statement posted before midnight of 11 January on the group's website.
Three months after the breakup of Bamboo, Azarcon, Cruz and Mercado reunited to form the band "Hijo" [pronounced as ee'-ho] (a Spanish word that pertains to a male human offspring or a son). The new band is composed of Nathan Azarcon on vocals and bass, Ira Cruz on guitar, and Vic Mercado on drums. The band also includes Junji Lerma on guitar and Jay-O Orduna on keyboard synthesizer and backing vocals. They performed their first gig at Route 196 on 16 April 2011. In 2012, Orduna was replaced by Wowee Posadas to play keyboards and provide backing vocals. Years after Hijo was formed, other band members left the band and left Azarcon as the sole member. Azarcon posted on his Facebook account that new members will be introduced in 2015. However, in 2015, Azarcon, Cruz, and Lerma reunited while Posadas haven't returned and drummer Vic Mercado was replaced with Paolo Manuel but the reunion was short-lived. Sometime in 2010, Nathan's brother Nick left his band Sinosikat? while Nathan's former bandmate Ira Cruz became the new guitarist for Sinosikat?. Nathan posted teasers on Facebook of his new band called "Disband" which features Bea Lao of General Luna as the drummer. Nathan then later posted that instead of renaming the band, it will still bear the name Hijo but this time it would be called Hijo 2.0. The band's music influence and genre is described by critics as "alternative metal" however the band rather label themselves as "Kung-Fu rock".
On January 9, 2016, Azarcon re-united with his former Rivermaya co-members, Perf de Castro, Mark Escueta and Rico Blanco for a "secret mini semi-reunion", following de Castro's gig at 19 East, Taguig City. Months later, Azarcon returned full-time to the band replacing Norby David for the first time since his departure in 2001.
Azarcon is a member of the Tau Gamma Phi Triskelion Grand Fraternity.
Azarcon has been known to use Fender, Music Man and Modulus bass guitars. He now uses Warwick basses exclusivelyRivermaya
