Lorraine Hunt's voice is incredibly beautiful, and very recognizable.  It is simply impossible to mistake her for anybody else.  Her best register is mezzo, and she generally sings low-tessitura parts in which she can be very  effective.  Yet, her voice is not low enough (plus it is too feminine) in  order to sing male roles convincingly.  Unfortunately also, she has quite a  bit of vibrato in her upper register where her voice can spread  uncomfortably when pushed.  Nevertheless, the sheer beauty of her timbre  compensates for the occasional technical flaw.  I enjoyed this disc, but I  most cherish Lorraine Hunt's performances as Medee and Phaedra in two  stunning recordings with Les Arts Florissants.
