The transitions on these work rather well...
Think I'll leave it at this-by the time this lot have played I'll be worn out or stuffed it from going too fast
So far I've got (in this order):-
Carl Orff-O Fortuna
Type O Negative-Everyone I Love is Dead
Bach-Toccata and Fugue in D minor
Trivium-Drowned and Torn Asunder
Mussorgsky-Night on Bare Mountain
Bal Sagoth-Black Dragons Soar above the Mountain of Shadows
Marilyn Manson-Burning Flag
Soundgarden-Jesus Christ Pose
Iron Maiden-Rime of the Ancient Mariner
Wagner-Ride of the Valkyries.
And just to kill any appreciation of anything else because very little compares to it...
Iron Maiden-Phantom of the Opera.
