Andrea Bocelli may have headlined the concert Thursday night at Gund Arena in Cleveland, but the stage belonged to guest soprano Ana Maria Martinez and the World Festival Symphony Orchestra. Vivid and charismatic, Martinez showed she could have the entire stage to herself. And sometimes she did, as she participated in eight of the 16 songs programmed, five of them being solo.Her singing was both inspiring and emotional, adding more than just another great voice to the show. She included several striking variations of tones and remarkable stage presence.The soprano’s acting was noteworthy when pairing up with Bocelli, an Italian tenor. But it was by herself that she brought her opera singer credentials to surface, delighting the fans in the nearly sold out arena.The Orchestra, conducted by Steven Mercurio, proved its capability of playing with Bocelli, who retains many say, one of the greatest opera voices of all time. It provided a splendid presentation both when performing with the tenor and Martinez, but also when performing by itself.When playing solely on stage – during Bocelli’s breaks -and especially on famous songs like “Manon Lescaut” and “Cavalleria Rusticana,” the orchestra got more positive response from the audience than the tenor.Bocelli’s stardom got obscured not only by the precious display of the orchestra and Martinez, but also because of his pallid stage presence, still one of his most obvious problems. The blind tenor, who has been trying to become noted as a true opera singer, lacked the acting skills necessary for the task. His physical hardships to move ended up occluding his presentation. When contrasted with the theatrical performance of Martinez, his difficulties became even more exposed.The tenor, who has had huge success on the pop charts especially with his album “Romanza,” had in the program pieces by masters of classical music Puccini and Verdi, showing his recent classical trend.Yet, by not singing some of his greatest hits, like “Miserere” and “Rapsodia,” he may have come up short of what his fans wanted to see. He tried to innovate in order to become more recognized as an opera singer, but by doing this he got away from his strongest pieces.If it had not been for the triple encore, in which he staged fan-favorite songs like “Con te Partiro” and Nessun Dorma,” his presentation would have been even more disappointing.By the end of the night, true Bocelli fans may have been a bit dissatisfied, wishing they had seen more of the tenor’s old style – the one that got him in star status. Laying that aside, opera fans in general had to be more than pleased with the three-star show.
