BBC NEWS | UK | Wales | South East Wales | Zep singer returns to solo roots
The former Led Zeppelin frontman returned to Rockfield, near Monmouth, to mark the 25th anniversary of his debut album after the group broke up.
He was reunited with guitarist Robbie Blunt and keyboard player Jez Woodruffe for a book on the studio.
The visit was arranged by journalist Jeff Collins, who is compiling a history of the studio, which was founded in the mid-1960s by brothers Kingsley and Charles Ward.
Plant, 57, recalled how he arrived at Rockfield 25 years ago this week, in the wake of Zeppelin's split following the death of the band's drummer John Bonham.
But he told Collins he had not been sure he would make the transition from globe-trotting rock star to a musician with a solo career.
He said: "As far as expectation went, I mean at the age of 32 when your career is finished, anything that came after that was a bonus really.
But it was Plant's decision to record at Rockfield which gave the studios enhanced credibility with generations of musicians, said Jeff Collins.
He said: "Of all the artists that have worked there, the person most talked about is Robert Plant, having been in one of the world's biggest and most successful bands.
"A lot of musicians have seen that his albums were recorded at Rockfield and thought, 'if it was good enough for him, it's good enough for me'."
Plant's 2006 schedule includes gigs in Milan and the USA at the end of May and June and a one-off performance with former Led Zeppelin guitarist Jimmy Page at the Montreux festival in July.
Hope Robert gets in the studio again and start recording another magnificent record soon.
