Rhythm and feel IS musicality. It's the kind of musical talent that cannot be taught. And playing with an orchestra is a two part process. Yes, the orchestra does have to get in swing with the band, but it also works the other way. And for the orchestra to be able to play with the band, the band needs to be playing in a way which is easy to pick up.

I do also play in a band. I sing Metallica, Muse, Bon Jovi etc.
