I'm a fan and still listen to some of their albums. I really admire and enjoy Karen's voice and, especially, Richard's arrangements and production.
But, world class singer or drummer? If someone can point me to examples of her world-class drumming, I'd like to hear them. And her voice....pretty limited range, pretty limited dynamics and color.
Pleasant, good, even very good, but I can't stretch my admiration to the world class level.
