There doesn't seem to be an official web site for the festival or the Bill Monroe Museum. The Bill Monroe Blugrass Festival has been taking place in Beanblossom for over thirty years now. They've been holding it in early to mid June the last few years, at least, although there are maybe half a dozen other concerts and festivals held at the Bill Monroe Museum and Festival Grounds throughout the year. Give them a call if you're heading to this neck of the woods and want to hear some authentic American roots music. Camping is available on the grounds and there's a museum and gift shop open most days.
Tickets are typically on sale at the gate.
Children younger than 12 were free with an adult.
