We bought box seats (140 Euro/ticket) to an orchestral performance of Nabucco, with Riccardo Muti conducting and 8 soloists from the Rome Opera House performing the parts, and they were worth every cent. The acoustics and performance were wonderful (as were the drinking in the street during the intermission and the stylishly dressed people). Highly recommended for those who enjoy impeccably performed classical concerts. (I attended in a wheelchair (broken ankle), and with the elevator to the 2nd floor, I only had to walk up 5 steps to get to my seat.)
