The above list of opera performances by Luciano Pavarotti is from the archives of the San Francisco Opera. Most of these were in the days of Kurt Herbert Adler who retired in 1981, including all of the debut performances in seven roles. This was Adler's special gift--he offered European singers the opportunity to sing something they had not sung before, and lured them from across the ocean.
I know I was in the audience for the 1988 performance of La Bohème with Mirela Freni, the performance on the commercial DVD.
"Debut in role" means this is the first time he sang that role.
