There is nothing wrong with excitement. That emotion was the main reason for the birth of rock in the first place. Rock was more exciting, in 1955, than Rosemary Clooney. The Texture school has developed more recently. It was called 'head music' or 'psychedelic rock' at one point, but now those names seem inappropriate.

The development of this school led inevitably to jazz and classical music. It isn't rock. It doesn't have the requisite incessant beat. The band's duets - between guitar and flute, guitar and table, table and bass, for example, were exquisite. Procol was headliner.
