1991–1999: Early success with Radiohead In 1991, On a Friday signed a record contract with
EMI and changed their name to Radiohead. For their second album,
The Bends (1995), the guitarists' roles were more divided, with Yorke generally playing
rhythm, Greenwood
lead and Ed O'Brien providing effects.
The Bends received positive reviews and elevated Radiohead's profile. ,
Jonny Greenwood, Ed O'Brien, and
Phil Selway discussing
OK Computer in 1997 Radiohead's third album,
OK Computer (1997), brought them international fame and is often acclaimed as one of the best albums of all time. O'Brien used less
distortion and more
delay and other effects, creating a sound that was "more about textures". He became depressed during the extensive
OK Computer tour, but focused on supporting Yorke. After the tour, he returned to Oxford, used large amounts of drugs and fell further into depression. He said: "I was single, on my own … I was the lowest I've ever been. It was the irony as well – you're at the top, that old cliché."
2000–2007: Developing sound and 7 Worlds Collide Radiohead's next albums,
Kid A (2000) and
Amnesiac (2001), marked a dramatic change in sound, incorporating influences from
electronic music,
classical music,
jazz and
krautrock. O'Brien initially struggled with the change, saying: "It's scary – everyone feels insecure. I'm a guitarist and suddenly it's like, well, there are no guitars on this track, or no drums." He began using
effects units more extensively to process his guitar, creating synthesiser-like sounds. O'Brien kept an online diary of Radiohead's progress. With Selway and other musicians, O'Brien toured and recorded with
Neil Finn as part of the
7 Worlds Collide project, providing guitar and backing vocals. He appeared in a 2011 episode of the
BBC Radio 5 Live sports programme
Fighting Talk in support of
Record Shop Day. He contributed guitar to the 2003
Asian Dub Foundation album
Enemy of the Enemy. During the sessions for Radiohead's seventh album,
In Rainbows (2007), O'Brien believed Radiohead might never record another album. He said later: "One of my mantras throughout the recording was, 'This is the last time I'm doing this. I'll never summon up the energy to do this again. So I'm going to put everything I can into it.'" He was motivated by a desire to secure Radiohead's legacy as a great band, and said in 2008: "In my view, we've made three really great records,
The Bends,
OK Computer and
Kid A. What we needed was another great record just to seal it." In 2013, O'Brien cofounded the Laundry, a workspace, restaurant and nightclub converted from a laundry in
London Fields. In 2019,
Hackney Council announced that the building would be demolished to make way for luxury flats. In 2014, O'Brien and Selway signed an open letter protesting a ban on guitars in British prisons and stating that music was important for
rehabilitation. In 2012 and 2013, O'Brien and his family lived on a farm near
Ubatuba, where he began working on solo music. Following the tour, Radiohead went on hiatus. In April, O'Brien joined the
RSPB Let Nature Sing project, which aimed to get
birdsong into the UK charts to raise awareness of the decline in Britain's birdlife. O'Brien released his first solo music under the name EOB. His solo debut, the non-album track "Santa Teresa", was released on 4 October, 2019.
Stereogum described it as a "haunting"
ambient instrumental in the style of
Brian Eno and
Fennesz. O'Brien released his debut solo album,
Earth, on 17 April 2020 on
Capitol Records to positive reviews. It features the Radiohead bassist, Colin Greenwood, plus the drummer
Omar Hakim, the
Invisible members
Nathan East and
Dave Okumu, the folk singer
Laura Marling, the
Portishead guitarist
Adrian Utley and the
Wilco drummer
Glenn Kotche. The first track, "
Brasil", was released on 5 December 2019, followed by "Shangri-La" on 6 February. He said he intended
Earth to be the first album in a trilogy. A larger tour was cancelled due to the
COVID-19 pandemic. In 2020, O'Brien contributed to Ear Opener, an online video course aimed at helping young people write music. That November, he gave evidence to a
DCMS Committee inquiry into the impact of
streaming on the music industry. He said he wanted to speak for less successful artists, who he felt were exploited. O'Brien contributed a remix of
Paul McCartney's song "Slidin to the 2021 remix album
McCartney III Imagined. 2022–present: Blue Morpho and Radiohead reunion During Radiohead's hiatus, O'Brien became depressed and felt he was finished with Radiohead. He took solace in making music alone, going for long walks in his home in Wales, and using
magic mushrooms with friends in
Dartmoor. O'Brien was one of more than 1,000 musicians to support
Is This What We Want?, an album of silence released on 25 February protesting the use of
unlicensed copyrighted work to train AI. O'Brien criticised Israel following the outbreak of the
Gaza war and expressed support for Palestinians, calling for the
release of hostages and a
ceasefire. O'Brien's second solo album,
Blue Morpho, is due for release in May 2026. It was produced by
Paul Epworth and features musicians including Selway, Okumu,
Shabaka Hutchings and
Tõnu Kõrvits. O'Brien said that, for
Earth, he had not wanted to "put himself front and centre", but that now he had "stopped hiding". He said he had overcome his songwriting insecurities and was now more relaxed. ==Musicianship==
