People said that Sonny Stitt sounded like Charlie Parker (on alto).
I wouldn’t say that’s a bad thing.
But you want your own sound, so he started playing tenor more and people said that he didn’t sound just like Parker anymore.
Charlie Parker was a pioneer in bebop, but Sonny Stitt took the style and cleaned it up.
I like listening to Stitt more than Charlie Parker myself, it’s more polished and I like his sound better.
Not to take away from Charlie Parker’s glory of course.
