Nikolaus Harnoncourt's 1974 version, the first recording without cuts, used period instruments in an effort to achieve a more authentic sound, although Denis Arnold has criticised Harnoncourt's "over-ornamentation" of the score, particularly his use of oboe and trumpet flourishes. Arnold showed more enthusiasm for Alan Curtis's 1980 recording, live from La Fenice in Venice. Curtis uses a small band of strings, recorders and continuo, with a trumpets reserved for the final coronation scene. Subsequent recordings have tended to follow the path of authenticity, with versions from baroque specialists including Richard Hickox and the City of London Baroque Sinfonia (1988), René Jacobs and Concerto Vocale (1990), and John Eliot Gardiner with the English Baroque Soloists. Sergio Vartolo's production of the opera at Pigna, Corsica, was recorded for Brilliant Classics in 2004. A feature of this recording is the casting of a soprano Nerone in acts I and III, and a tenor Nerone in act II, to allow for the differing vocal requirements of the role in these acts. Vartolo accepts that "a staged performance would almost certainly require a different approach".
