The best event I have ever been to would definitely be the one in India, a musical night by an Indian classical singer.  The music form was Hindustani, which is the Indian word for North Indian music.  There was the tabla and the vocals.  It is hard to say which of the two surpassed the other.  That was the first glimpse of the rich Indian culture that I had.  That night made me envy the Indians who have the privilege to such shows as often as they wish.  For me, I hope it at least turns out to be more than a onetime experience.
