ive been playing over voodoo chile for weeks and for pure adrenaline i cant find anythign close to it.

some pink floyd ones are goof but they are far to depressing same with the led zep ones i can find.

And I am totally bored of the generic blues backing tracks on youtube


cheers

Write one yourself. Then analyze what notes you can use over each chord or section.
This is also how you learn to write you own music.
