The Royal Hounds may be Las Vegas’ premier rockabilly trio, but the musicians’ high-energy antics can’t be confined to one city. On Saturday, Aug. 23, Danny Michel (guitar), Scott Hinds (bass) and Scott “Bramble” Billingsley (drums) will continue a swing through the South to promote debut album “I’m in Love With a Zombie” with a performance at the Rockabilly Rock Out and Cruise In at Thunder Creek Harley-Davidson, 7720 Lee Highway. Set for noon to 5 p.m., the event includes a bike and car show, pinup contest ($1,000 in cash prizes), tattoo contest and vendors. Admission is free.
