I still like to sing about 50 performances per year of operas and concerts. It's difficult to sing my repertoire more than three times a week. Gurrelieder , for example, is a big workout. It is funny, I don't feel old enough to give advice. A few years ago, I was speaking with a record executive about a project.
Young singers have to figure out who has earned the right to give advice.
It is very important for young singers to know themselves and who their real friends are. Too often young artists are led in different directions by friends, teachers and coaches. You have to figure out who has earned the right to say the difficult things. My wife is a big part of that for me. You also need a teacher and management you can trust.
