Let’s just call them the Von Trapps, shall we? Because between Miley, achy-breaky dad Billy Ray, stepbrother Trace of top-40 emo-pop hair bears Metro Station, and now 22-year-old Brandi, the hills — from Nashville to Los Angeles — are alive with the sound of musical Cyruses.

Brandi’s band Frank and Derol, which includes lead singer Codi Caraco and Secret Life of the American Teenager star Megan Park on bass and vocals, recently made their stage debut opening for Billy Ray at L.A.’s House of Blues, though Brandi isn’t exactly new to the game; she previously served as a guitarist for Miley on tour and on Hannah Montana.

According to a piece today on, the all-girl pop outfit formed less than a year ago after meeting at a family friend’s birthday party, and they plan to keep performing this summer in pursuit of a record-label deal.

Their sound (as evidenced on their Myspace page, at least) is actually surprisingly pretty and subtle, considering the family geneology — gentle, girlish harmonies over floaty melodies and shimmering synths, like some unlikely lovechild of Wilson Phillips and the Postal Service.

Watch the band introduce themselves below, and tell us which Cyrus gets your vote: Brandi, Miley, Trace, Billy Ray, this little minx right here (not singing yet, but we’re counting the days!) — or none of the above?
