Chris Martin has long been known as a reluctant rock star, a man who prefers a quiet life of yoga practice and vegetarian dinners at home rather than a red carpet lifestyle.
Yesterday, the Coldplay frontman further consolidated his reputation as the quiet man of pop, by walking out of an interview for a Radio 4 arts programme, Front Row, saying he didn't like "having to talk about things".
The musician, 31, abandoned the interview to promote Coldplay's new album nine minutes into the recording, telling the programme's presenter, John Wilson, that he was "not really enjoying this".
The album, Viva la Vida (or Death to All his Friends), which was released on Thursday, is set to become one of the fastest – and biggest-selling records in chart history. After selling 125,000 copies in its first day, it could see Coldplay outsell their 2005 album X&Y, which sold 465,000 in its first week.
The new album is almost certain to take the top spot in the album chart on Sunday. The group are EMI's best-selling act and the latest album is said to be crucial for the record company, which is attempting to revive its fortunes with more people downloading music illegally.
A BBC report said Martin appeared uncomfortable from the start of the interview. Asked about a speech he made at a music awards ceremony in 2005 when he said the band would be away "for a very long time", Martin said: "I always say stupid things and I think Radio 4 is the place that will most remind me of that."
When Wilson asked whether the album's full title reflected the band's obsession with death, it was received with some hostility by Martin, who accused Wilson of being manipulative.
"I wouldn't agree with you there at all, no. I'd say you're intentionally twisting me into saying something I don't really mean," he said.
Martin then appeared to hesitate after Wilson asked him about the inspiration for lyrics of a song dealing with the subject of a deposed dictator.
When Wilson asked that Martin move closer to the microphone, the musician asked: "Can I have two minutes – is that all right?" before walking out.
Wilson asked him whether he was feeling under pressure, to which Martin said: "No, no ... yes, I just don't like to talk about things."
Wilson turned to Coldplay's drummer, Will Champion, asking: "Have I upset him?" Champion replied: "I don't think so."
Champion continued with the interview until Martin came back into the studio to answer a final question about whether he was attempting to find new musical territory with the album. Martin answered simply: "Um, yes, yes, yes ... exactly."
It is not the first time thatMartin has shown a strong aversion to media attention, having previously scuffled with photographers in London and New York.
