This three-disk collection provides a sampler from the whole range of Handel's operatic career (1705-1741). Dame Emma Kirkby is beyond praise; on the second disk she is beautifully matched with Catherine Bott in selections featuring the "rival queens" of the London opera during the 1726-1728 seasons. Ray Goodman and the Brandenburg Consort provide sensitive accompaniment: the delicacy of "V'adoro pupille," Cleopatra's seduction aria from Guilio Cesare is outstanding. I'd also point to the selection from Alcina as a great example of Handel's dramatic writing; it he'd written like this more often, the operas might not have needed revivial.
A few well known arias, such as "Ombra ma fu" won't be found in this set, as they were intended for another (lower) vocal type.
