When I think of Ronstadt's most moving vocals, two songs compete for the top spot, Long Long Time and Different Drum. They both have a slight country-tinged sadness and longing mixed with some of the most powerful pipes this side of opera. The note at 2:40 on the first video still gives me chills.
Linda Ronstadt isn't in the Rock and Roll Hall of Fame. Let that percolate for a bit. Is it sexism? Is it because she was "only" a singer? I'm not going to start bashing who is in the HOF to make my point, but Ronstadt was a dynamic vocalist who handled a range of genres and had commercial as well as critical success. What else do they want?
