Xabi San Martín

Xabi San Martín is a Spanish composer and keyboardist, best known as the principal songwriter and keyboardist for the pop group La Oreja de Van Gogh. He has been the band's creative anchor since its founding in 1996, writing the melodies and arrangements that defined their sound across multiple vocalist eras.

As of 2026, he is back in the spotlight with the band's reunion with original vocalist Amaia Montero, a pairing that has long fascinated fans. His understated presence contrasts with the emotional weight of his compositions, which have made La Oreja de Van Gogh one of Spain's most beloved pop acts. With over 800 composer credits, his influence on Spanish pop is immense. [edit]

Born and raised in San Sebastián, a city with a rich musical heritage in the Basque Country, Xabi San Martín grew up surrounded by music. His parents, Eduardo San Martín and Mila Beldarrain, encouraged his early interest, and he was the eldest of two children. Details of his childhood are scarce, but his path took a decisive turn in 1996 when he co-founded La Oreja de Van Gogh with friends in his hometown.

From the start, he took on the dual role of keyboardist and principal composer. His early compositions, crafted in the band's formative years, already showed a knack for catchy, emotionally resonant pop melodies. The band's first recordings, including the film Novios in 1999, showcased his songwriting. Before the breakthrough, he honed his skills in local venues, developing the sound that would soon capture a national audience. [edit]

La Oreja de Van Gogh's self-titled debut album, released in 1998, launched them into the Spanish pop mainstream, and Xabi San Martín's compositions were at the heart of hits like "El 28." The band's success grew with each album through the 2000s, selling millions of records across Spain and Latin America. His songwriting credits expanded to include films like You Are the One (2006) and Valentina (2017), showing his versatility.

In 2016, he performed with the band at the Kursaal Auditorium in San Sebastián, presenting El Planeta Imaginario. The band continued to tour, drawing over 4,000 fans in Salobreña in 2024. After vocalist Leire Martínez left in October 2024, the band announced Amaia Montero's return in October 2025, with a new tour. San Martín and Montero appeared together in Las Vegas later that month, and in July 2026 they performed at Córdoba Live, where a kiss between them went viral. His role as the band's constant creative force has been pivotal in this new chapter. [edit]

Xabi San Martín is perceived as the quiet genius behind La Oreja de Van Gogh. Fans often describe him and Amaia Montero as "todo lo que está bien" (everything that is right) about the band, a sentiment echoed in fan club videos and social media. His public persona is understated, preferring to let his music speak. The viral kiss at Córdoba Live in 2026 intensified public fascination with his personal dynamic with Montero, but he remains an enigmatic figure, rarely giving interviews or engaging in solo media appearances. [edit]

The public perception of Xabi San Martín is defined by a distinct duality: he remains the quiet, enigmatic architect behind one of Spain's most beloved pop acts while simultaneously serving as the focal point for intense emotional speculation regarding his personal history with original vocalist Amaia Montero. Unlike many peers whose fame relies on constant media visibility, San Martín cultivates an aura of mystery that has only deepened following the band's reunion and subsequent viral moments. The fanbase, often described collectively through their support of La Oreja de Van Gogh rather than as a distinct group dedicated solely to him, engages in a unique form of devotion centered on the narrative of the band's reunions and the hidden meanings within San Martín's compositions. There are no documented organized campaigns, street shut-downs, or specific rituals attributed exclusively to his individual persona; instead, the collective energy of the audience channels its fervor through the broader mythology of the group's lineup changes and the iconic return of Montero. This dynamic was crystallized during a live performance at the Córdoba Live festival, where a spontaneous kiss between the composer and the singer transcended a simple performance moment to become a defining cultural touchstone for the era. Despite this high-profile attention, the community lacks a formal name, operating instead as a diffuse network of listeners who track the band's evolution through official channels. While San Martín is a founding member with a decades-long tenure, his global standing reflects the success of the ensemble rather than solo stardom. According to the August 2026 evaluation by iFANN, Xabi San Martín is currently not ranked in the Global Top 1,000 or any Top-100 scope list, reflecting his status as a highly influential figure without a placement in the current published rankings.[edit]

Xabier San Martín Beldarrain, born May 20, 1977, in San Sebastián, Guipúzcoa, serves as the creative anchor for La Oreja de Van Gogh alongside his roles as keyboardist and composer. His professional footprint is substantial, with accumulated credits totaling 805 compositions, 185 lyrics, 17 keyboard performances, and 13 production projects according to industry databases. He has been nominated for four Latin Grammy Awards, though no wins have been confirmed to date. A persistent piece of lore among fans involves the song "Tan Guapa," which San Martín dedicated to Amaia Montero, sparking endless speculation about its concealed significance. In 2014, he showcased his versatility by playing the theremin during a live performance at the Teatro Gran Rex in Buenos Aires. The narrative of his career reached a new chapter when he performed a historic duet of "Tan Guapa" with Montero during their reunion tour, reuniting voices that had previously sung the track separately. This moment gained further traction after a widely circulated incident at the Córdoba Live festival, where a spontaneous kiss between the two went viral, intensifying public fascination with their dynamic. Despite his fame, he maintains a low-profile social media presence, directing most attention through the band's official channels.[edit]

Per iFANN's editorial analysis, Xabi San Martín's net worth is estimated at $4 Million as of 2026. This valuation reflects the financial stability derived from his nearly three-decade tenure with La Oreja de Van Gogh, during which the group has sold millions of albums worldwide. A significant portion of his wealth stems from songwriting royalties generated by the band's extensive discography, ensuring a consistent revenue stream across multiple eras. Beyond composition, he generates income through live performances and touring activities. His portfolio also includes earnings from his work as a producer on 13 distinct projects outside of his primary songwriting duties. This long-standing relationship with the band has solidified his economic position, allowing him to maintain a steady financial trajectory despite the fluctuating nature of the music industry.[edit]
