Simple,
What are your favorite instrumental songs of all time?
My absolute favorite instrumental is "Orion" by Metallica.
My other favorites are:
"YYZ" - Rush
"Jessica" - Allman Brothers
"Frankenstein" - Edgar Winter Group
"Jordan" - Buckethead
"Moby Dick" - Led Zeppelin
More I could list, but it would take up too much space.
What say you all?
