Apparently "hootenanny" used to be a synonym for a "thingumabob," but most folks now likely think of a folk music throw-down when they hear the word. Which is entirely not what tonight's Hootenanny for the Arts event is from 6:30 to 9 at The Mansion (20 N. Tejon St., coppercolo.org). Instead, it's a fundraiser for COPPeR's Peak Arts Fund and post-production of the local film Creep! Area visual artists, dancers and musicians will perform and $25 tickets ($30 at the door) include appetizers and three drink tickets. The finest Rat Pack-era costume wins a trip to Las Vegas, plus a new Creep! trailer will screen, and graphic mastermind Langdon Foss will provide 100 limited-edition Creep! tribute posters ($20). Guess all that newly defines a hootenanny. — Matthew Schniper
