On Kimberly Perry's iPod, a very cheesy version of “Happy Birthday” that was used for their mom's birthday party can be found.“I'm kind of embarrassed to say it cost me $1.29,” said Kimberly Perry, the oldest sibling, who sings the lead vocal and plays the rhythm guitar and piano.The siblings enjoy teasing one another.“As the road gets boring, we tend to push each other's buttons for a little excitement,” said Neil Perry, who plays the mandolin, drums, accordion and does background vocals.Reid Perry, 22, plays bass guitar and background vocals.Their mom is usually there to keep them in line though, joked Kimberly Perry.The advantages of being a sibling band outweigh the disadvantages, Kimberly Perry said. The three know each other so well they share an unspoken language that comes in handy when performing on stage or recording, she said.The siblings have 13 years of experience traveling together, but they weren't always a family band, she said.“The guys are younger than me, so when we first started traveling, they had their own band and they opened up for my band,” Kimberly Perry said.After a few years of traveling in Alabama, the Perry siblings began to work on an independent project that featured music with strong Rolling Stones influences, Kimberly Perry said. The siblings grew up in a household with strong musical influences from a dad who loved rock and a mom who loved country, she said.
