The lead singer ego is pretty well known, but the band I play upright in is retooling with a new singer and new drummer. The singer has a fantastic voice, but what's interesting is that she's a bit of a perfectionist and doesn't have the confidence to be loud, proud, and wrong when she forgets a word or makes a mistake. Maybe she will develop an ego over time as she settles in. Anyway, she has the opposite problem as too much ego, at least for now.
