Ingpen, conductor Georg Solti's agent during the 1950s,[3] became artistic administrator of the Royal Opera House in Covent Garden in 1961 at Solti's request,[1][3] after which Ingpen & Williams was managed by Howard Hartog,[4][5] editor of European Music in the Twentieth Century[6] with help from his wife, the concert pianist Margaret Kitchin.
It was Joan Ingpen who put lyric tenorLuciano Pavarotti on the international opera map in 1963.[7][8][9] She hired him to cover for the role of Rodolfo in La bohème in the event that Giuseppe Di Stefano was unable to perform. Di Stefano withdrew on the second night, and Pavarotti's more than twenty five performances drew great acclaim.
In September 2016 Ingpen and Williams Limited changed its company name to Groves Artists Limited, and continues to manage artists such as Sir Mark Elder, Sir Richard Armstrong and Graham Vick.
