And as if to prove it, you can hear a snip-it of Mustaine - along with the San Diego Symphony - slaughtering Wagner below.
All part of a "Symphony Interrupted", which saw Mustaine perform Richard Wagner's "Ride Of The Valkyries" with the orchestra, as well as solos of Vivaldi's concertos from "The Four Seasons", plus Bach's classic "Air".
Said Mustaine of Vivaldi: ""But for me, my particular — the way we were drawn to the Vivaldi stuff was because it was kind of in a sad kind of modality. I don't even know — I'm self-taught — so I don't even know what I'm doing, I just do it. So, listening to (Rhoads') solos in there, they just had this color, this attitude to it, that really appeals to me. Like when I was listening to some of the stuff that Randy would do over Ozzy's songwriting."
Oh! And should you be interested he has promised more in the future. Be afraid. Very afraid!
Why are we reminded of Paul Hindemith's Overture to the Flying Dutchman as Sight-read by a Bad Spa Orchestra at 7 in the Morning by the Well?
