In this tribute to the great nineteenth century mezzo-soprano, Maria Malibran, Cecilia Bartoli sings selections from the repertoire for which Malibran was known.

Malibran also ventured into soprano roles, and Bartoli bravely and entirely successfully follows her into that territory.

In fact, the primary impression the CD creates is astonishment and awe at the extraordinary range of these selections, and Bartoli's ease, absolute security, and seamless delivery, from above the treble staff to the middle of the bass staff.

Hummel's Air à la Tirolienne avec variations may not be a musical masterpiece, but as a showcase for Bartoli's range, dizzying coloratura, and yodeling ability, it is breathtaking.

The collection is made up of much music written especially for Malibran, and besides giving Bartoli a chance to dazzle, the pieces are irrefutable testimony to how remarkable an artist Malibran must have been.

Some of the most striking pieces are the recitative and aria from her father's opera La Figlia dell'aria, a concert scena and aria by Mendelssohn, and a song by Malibran herself, which requires both a command of extended vocal techniques and a sense of humor, and Bartoli brings it off with panache.

One of the strengths of the collection is its inclusion of so much repertoire that's virtually unknown today.

Only three excerpts from Bellini operas and one by Rossini are likely to be familiar to most opera lovers.

Bartoli's "Casta Diva" is a marvel of purity, restraint, and emotional vulnerability, and is by itself worth the price of the album.

Adam Fischer conducts Orchestra La Scintilla in lively accompaniments to Bartoli's vibrant and supple performances.

The CD should be of strong interest to any fans of early nineteenth century coloratura repertoire.
