Edward John O'Brien, born on 15 April 1968, is an English guitarist, songwriter, and a foundational member of the iconic rock band Radiohead. Known for his atmospheric and textural approach to the guitar, O'Brien has carved out a unique identity within one of the most critically acclaimed acts in modern music history. His role, as he has often described it, is to "service the songs" and support the primary songwriter, Thom Yorke, creating a sonic landscape that is both expansive and meticulously crafted. Rolling Stone has twice recognized his genius, naming him among the greatest guitarists of all time in both 2010 and 2023, a testament to his enduring influence on the instrument and the genre.

O'Brien’s journey began at Abingdon School in Oxfordshire, England, where he formed Radiohead alongside his schoolmates. The band, which would go on to redefine alternative rock, released landmark albums that pushed the boundaries of musical experimentation. While Thom Yorke and Jonny Greenwood often took the spotlight for their songwriting and lead guitar work, O'Brien’s contributions were indispensable. He specialized in creating ambient sounds and textures using a variety of effects pedals, sustain units, and the EBow, a device that produces an infinite, violin-like sustain. His backing vocals and sonic depth provided the ethereal foundation that became a hallmark of Radiohead's sound, from the anthemic rock of the 1990s to the electronic and experimental explorations of the 2000s.

Beyond his work with Radiohead, O'Brien has engaged in several notable side projects that highlight his versatility and collaborative spirit. In the 2000s, he toured and recorded with the 7 Worlds Collide project, a collective of musicians organized by Neil Finn that included his Radiohead bandmate Philip Selway. These sessions allowed him to explore a more collaborative and improvisational environment, further expanding his musical repertoire. His dedication to social and environmental causes has also been a consistent theme throughout his career, as he has actively campaigned on issues including climate change and artist rights, using his platform to advocate for meaningful change.

In 2020, O'Brien stepped into the spotlight as a solo artist with the release of his debut album, Earth, under the moniker EOB. The record was heavily inspired by his time living in Brazil and his immersive experiences attending Carnival, infusing his signature guitar work with South American rhythms and a more personal, introspective lyrical focus. The album was met with critical praise, showcasing a more direct and song-oriented side of his artistry. Unfortunately, a solo tour in support of the album was cut short due to the outbreak of the COVID-19 pandemic, but the project solidified his status as a formidable creative force in his own right. He followed up with his second album, Blue Morpho, released in May 2026, demonstrating a continued evolution of his solo voice.

O'Brien’s legacy was further cemented in 2019 when he was inducted into the Rock and Roll Hall of Fame as a member of Radiohead, an honor that acknowledged the band's monumental impact on music. Throughout his career, he has remained a figure of quiet intensity and profound creativity, balancing his role as a supporting player with his ambitions as a solo artist. Whether crafting dense sonic backdrops for Radiohead or exploring new rhythmic territories on his own records, Ed O'Brien has proven himself to be an essential architect of modern rock music, continually pushing the boundaries of what the guitar can achieve.
