This weekend, the tenth annual Austin Celtic Festival will be held at Fiesta Gardens. It’s a great event for all ages, with plenty of Celtic music (from the uber-traditional to the not-at-all-traditional), dancing, theater, haggis, beer, highland games, and, of course, kilts! Tickets are $10 at the gate. If you can’t wait that long to get your Celtic groove on, festivities get underway tonight at the Cactus Cafe with a kickoff party featuring The Prodigals, and with local Irish band, The Tea Merchants, opening.
