Brooklyn’s macabre, folk-noir duo Charming Disaster have an appetite for all things grisly and ghoulish. Their songs tell tales of dastardly secretaries, paranormal romances and creepy carnival performers, with frequent references to murder, mayhem and the supernatural — albeit with a whimsical, lighthearted attitude. The pair keeps things simple with just ukulele and guitar, though their performances are known for theatrical panache. A 2014 episode of the oddball podcast “Welcome to Night Vale” featured their darkly sweet love song, “Ghost Story.” Their new album, Cautionary Tales, is out in April. Charming Disaster perform on Friday, March 24, at Radio Bean in Burlington.
