Lord Mount Charles, the man who hosted world famous music acts such as Queen and Bruce Springsteen at his Slane Castle home, has died aged 74.
Lord Mount Charles, who was custodian of the Irish castle in County Meath, died on Wednesday, after a "battle with cancer", his family said.
His idea to bring the globe's biggest stars to play huge gigs at the castle made Slane a byword for era-defining rock concerts.
They have been held periodically since 1981 and attracted the likes of U2, Bob Dylan and, most recently, Harry Styles.
In a statement, his family said he left behind an "extraordinary legacy as a passionate steward of Ireland's heritage, dedicating his life to preserving Slane Castle and transforming it into a beacon of culture, music, and community".
