Silvia is also a professional actress for stage and screen, as well as a writer and TV host.

“Orfeo’s despair is gloriously realised by Colloca whose rich yet pure and powerful mezzo soprano and dramatic acting range are ideally suited to the decision to make Orfeo an ambiguous and androgynous figure. She projects all the strengths of masculine and feminine and unabashed emotion in the early scenes making the tragedy quickly tangible” 
Diana Simmonds, Stage Noise

"...First, I must stress that the singing was superb. In particular, this production's Orfeo, alto Silvia Colloca (and yes, I checked, in the current-day near-total absence of castrati in the opera world, the role is now sung by an alto or a countertenor), has a room-filling voice of terrific versatility, gorgeous tone, and jaw-droppingly accurate pitch..." 

"I mention Colloca last because she is unquestionably the star of the show. Her warm, mellow, rich voice was matched only in its expressiveness by her acting, which was superb. A professional actress for stage and film as well as a singer, I was astonished to see what looked like real tears running down her face at one particularly poignant moment. She, probably more than anyone, really made the audience empathise with the cruel tragedy of love and death. She reached the height of her expressiveness with her beautiful messa di voce and carefully chosen dynamic nuances just after Euridice’s second death. Only rarely does one come across such a true singer-actor."
