I might be misunderstanding your post. Did you take private lessons with Edman?
I’ve only heard Edman on the two YJM records he appears on. Great singer no doubt, not trying to diminish his singing ability at all, I just don’t think it’s at Freddie’s level based on having heard those albums only.
I took vocal lessons too.
Sure, there are a lot of excellent singers, but there’s another side to it. I’m aware of dozens of famous singers who can’t control their voices and pitch when performing live. Some are so bad that I can only believe their recording are the product of endless takes and pitch correction.
There’s also a lot of singers, particularly singer-songwriters who are themselves only passable vocalists.
I’m not arguing that Eric is a great singer. I think his voice is adequate. There are plenty better singers, but there are plenty worse too.
