Belle Epoque were a French screamo band. According to their official website, as of September 11, 2006 they are no more. There is also a Post-Hardcore band of the same name who released an EP "Our Bodies" in 2008.
[Editor Comment (You can edited this out when you review): But since there is no more French Belle Epoque, I think we need to transfer page to active Belle Epoque from Texas. Thank you.
