Moonlight Shadow, To France, Family Man, Foreign Affair... are just some of the songs by Mike Oldfield that topped the charts in the 80s. All of them have as a common denominator the incomparable voice of Scottish singer Maggie Reilly, a singer inseparable from the British composer's pop stage.

Maggie Reilly not only owes her international prestige to her work with Mike Oldfield. Her solo career includes great hits such as Everytime we Touch (which became a massive hit in 2006) and Tears in the Rain.

Maggie Reilly currently tours regularly in the UK and Germany.

Opus One is a project created to interpret the music of Mike Oldfield on the occasion of the fiftieth anniversary of the publication of his most important works. Its world premiere took place on May 25, 2023, the exact date of the 50th anniversary of the publication of Tubular Bells, with a live streaming concert that was watched by more than 4.500 people. It currently has more than 1.4 million views.

Their first public concert was in June 2023 at the Palau de la Música in Barcelona together with Maggie Reilly, with a total success both artistically and with the public. Subsequently, Opus One has performed at the Auditorio Nacional de Música in Madrid, the Cartoixa Center CITE in Seville or the Teatre Coliseum in Barcelona, ​​​​among other important concert halls, participating in competitions such as the Palau Fronteres cycle (2023 and 2024) or the Guitar BCN 2024.
