I'm always interested in suitable dance music for the Regency/Jane Austen era, but having expected that, I was very disappointed in The Pride & Prejudice Collection from the UK-based Pemberley Players that is subtitled "A Selection of Dances Popular in the 18th and 19th Centuries."
But first, the good parts:
The Pemberley Players are an English quintet under the leadership of David Fleming-Williams that specializes in playing country dance music. They have an absolutely lovely sound: a piano, two violins, a cello, an a flute. I suspect they aren't using an 18th-century piano, but I don't know enough about the difference in sound for it to matter for me. The strings are beautiful, and the instrument mix very suitable for the era. You can tell this is an experienced dance band: they keep their tempos steady and avoid artsy tricks that make things difficult for dancers. It's a lovely listening experience.
As a source of usable period dance music, however, it's got some problems.
