In the second half of the nineteenth century, Richard Wagner revolutionised opera which he saw as a total work of art with music part of a wider visual, poetic and, especially, dramatic experience. 'Das Rheingold' is the first of the four operas in his 'Ring Cycle'. This prelude describes the River Rhine, calm and majestic.
When Paul McCartney released his first post-Beatles solo album it didn't do well, at least with the critics. Compared to his radical bandmate John Lennon, he just seemed twee and lo-fi.
Many years later the album is seen as hugely influential. In fact the pendulum has swung on so much of his solo work. Even so, it is hard to believe no-one at the time thought 'Every Night' a great song.
