Ryland Davies was born in Cwm, Blaenau Gwent, to the steelworker Gethin Davies and his wife Joan (née Baker).[1] He was a rugby player in his youth and gained a schoolboys' international cap for Wales against both England and Scotland in the 1957–58 season.[1][2]
Davies appeared at the Scottish Opera in 1966 as Fenton in Verdi's Falstaff.[4] He was recognised when he appeared there as Ferrando, alongside Elizabeth Harwood as Fiordili and Janet Baker as Dorabella, in 1969.[1]
He performed the role of Essex in Britten's Gloriana in 1967 both at the Sadler's Wells Opera in London and in Lisbon.[4] He appeared at the Royal Opera House (ROH) first in 1969, as Hylas in Les Troyens by Berlioz, conducted by Colin Davis.[4][7] He performed there also as Don Ottavio in Mozart's Don Giovanni inn 1970,[8] Ferrando, Nemorino, Almaviva, Ernesto in Donizetti's Don Pasquale, Fenton, and Enéas in Massenet's Esclarmonde.[4][8] He returned to the house in 1994 to portray Le Duc in Massenet's Chérubin, playing who he described in a 1998 interview with Bruce Duffie as a "fussy-arsed little chap" who "boss[es] everybody around".[3] He returned to Cardiff the same year to appear as the Podestà in Mozart's La finta giardiniera.[1] His final role, at the ROH, was Alcindoro in Puccini's La bohème in 2015.[5]
He appeared in the United States first at the San Francisco Opera in 1970, as Ferrando, in collaboration with director Jean-Pierre Ponnelle.[1] He performed at the Metropolitan Opera (Met) in New York City from 1975 where his first role was again Ferrando.[4] He returned there the following year to perform as Count Almaviva.[10]
In his prime, the music critic Alan Blyth considers the Davies "had a sweet-toned, lyrical voice and excellent diction."[12] His voice was described as lyric with a specifically Italian sound.[4] Barry Millington from The Guardian noted "the sweetness and Italianate quality of his light voice, his effortless projection and mellifluous legato".[1]
Davies married mezzo-soprano Anne Howells in 1966;[1] they performed together, often as Dorabella and Ferrando, in Glyndebourne in 1969[6] and at their debut at the Met in 1975. The marriage ended in divorce in 1981.[1] He later married soprano Deborah Rees; they had a daughter, Emily.[1] They resided in Surrey.[5]
He recorded the role of Belmonte on a DVD from the 1980 Glyndebourne Festival, directed by Peter Wood and conducted by Gustav Kuhn, alongside Valerie Masterson as Konstanze; a reviewer described his "elegant lyric tenor" as "near ideal", rendering "Mozart's phrases and singing with excellent diction".[17] Davies was the tenor in a collection of sacred music by Mozart including the Vesperae solennes de confessore, with Kiri Te Kanawa as the soprano, with the London Symphony Chorus and Orchestra conducted by Colin Davis.[18] He was the tenor soloist in a 1988 recording of Mozart's Requiem, with soprano Helen Donath, alto Yvonne Minton, bass Gerd Nienstedt, the Alldis Choir and the BBC Symphony Orchestra conducted again by Davis. Reviewer Stanley Sadie from Gramophone wrote: "The solo singing is of a very high order with many exquisite moments afforded particularly by Helen Donath's sweet, ringing soprano and Ryland Davies's lyrical tenor (caught at its best)."[11]
In 2007 Davies took part in a live recording from the Salzburg Festival of Eugene Onegin, conducted by Daniel Barenboim, with Peter Mattei in the title role and Anna Samuil as Tatiana; a reviewer wrote: "Davies, in the 1970s and 1980s one of the finest lyric tenors around, now in his mid-sixties was a wonderful tragicomic Triquet with the voice still in fine fettle".[19]
