Rock + Orchestra

Somehow the combination of a Rock Band with an orchestra troupe sounds amazing. Take for example

Metallica + SF Symphony --> S & M
GnR (Live), esp their Live version of November Rain, Estranged
Parikrama with the tablas and Voilin played by Imran

There could be more groups who might have performed with orchestra troupe but i am unaware. If some1 knows, please let me know too
