3. Metallica - S&M
Don't worry, we're not in Fifty Shades territory - the title stands for Symphony & Metallica. This landmark recording from 1999 features the multi-million-selling metal band's songs being performed in collaboration with the San Francisco Symphony Orchestra under the direction of Michael Kamen. Not for the faint-hearted.
