"her extraordinary gifts of vocal prowess and dramatic interpretation have never ceased to astound me. All others who have had the privilege of witnessing one of her performances have been equally moved and impressed. Whether in operatic roles of Monteverdi or Cavalli, in songs of Debussy or Ravel, or in the cabaret masterpieces of Weill or Piaf, Ms. Chatzistamatiou brings the audience vividly into the world of the composition she is performing with astounding fervency and emotion. A performance of Ms. Chatzistamatiou is a life-altering event."

"I have collaborated with Mariangela in numerous chamber music projects and have admired her precision to stylistic matters and interpretation as well as her vocal flexibility when she flawlessly moves from singing Monteverdi’s Scherzi to interpreting Schönberg’s Pierrot Lunaire. She can be a tremendously diverse artist who easily passes from one style and genre to the next. She is meticulous when approaching text-music relationship, style, and interpretation. She has a fabulous stage presence and her commitment to text and music is outstanding."
