I know this may not count as a solo, but that violin type of playing on Led Zeppelin's "Kashmir" is 20th century Mozart.
My 72 year old mother, who is not a fan of metal, but loves early rock like Roy Orbison, heard Kashmir as a bumper song on a talk show and said it was beautiful - "who is this?".
She was surprised to find out who they were, and that was done by a bow on an electric guitar.
