Festival Orchestra

I do not have sufficient reliable knowledge about a specific organization called 'Festival Orchestra' without more detailed location information. 'Festival Orchestra' can refer to various ensembles partaking or forming specifically for music festivals, each with its own unique history and artistic focus. Such orchestras might be assembled for particular events or commissioned for festivals worldwide, often comprising freelance musicians or members from different established orchestras. To provide an accurate description, more detail, such as a specific festival or geographical location, would be necessary.
