(2-CD set) It's time for the ladies to step up for the second of our "high brow" classical additions to the Essential Collection. This set features the inimitable Maria Callas, arguably the most famous soprano of them all, Adelina Patti, Elizabeth Schwarzkopf and Victoria de los Angeles. It also features the great Contralto's Kathleen Ferrier, Britain's beloved who died tragically young, and Clara Butt, the statuesque beauty whose voice, according to Sir Thomas Beecham, could be heard across the English Channel. Listen and wonder at these great voices from another era.
