When it comes to classic rock cover bands, Yellow Brick Road is a Las Vegas staple. As the lead singer, Brody Dolyniuk spent 14 years belting out AC/DC and Van Halen tunes. Now the band is reuniting for a symphonic rock show (French horn and Led Zeppelin, anyone?) at The Smith Center on August 24. We talk to Brody about merging a 25-piece orchestra with laser lights and good, old-fashioned rock-and-roll.
