Jones was a fine Tosca and Opera Depot has the proof with four performances given between 1969 and 1974. I have not heard the '69 outing yet, but the three I have heard are a worthy addition to any opera nut's collection. Her voice isn't quite focused yet when she begins this Zurich show, but it steadies out within the first scene. Her "Vissi d'arte" is a model of how the aria should be performed with a beautiful, floated climax. She has no difficulties with any of the high notes and she captures Tosca's volatile nature with flair.Raimondoi was a veteran Cavaradossi by this point. There is little he doesn't know about how to shape this music and he sings very well indeed. Gobbi may be a little dry-voiced by this point (he'd been singing for 25 years); he's a menacing, sexy Scarpia, still managing to keep his portrayal fresh. He gives as good as he gets from his Tosca. The supporting cast is very good. Santi knows how the opera is supposed to go and conducts with style.The sound is described as fair to good, but aside from some tape hiss this one has the most consistently good sound of the three Jones' Toscas I've heard: there are no pops and clicks and no bleed-through from another performance.If you love Tosca and/or Jones, any one of these performances will satisfy you!
