Cajun Country singer Hunter Hayes has been making music since he was five, when his parents gifted him his own accordion, specially made for his tiny hands. After mastering the accordion and keyboard, Hayes moved on to mandolin, guitar, bass, and percussion, establishing his own recording set-up before he could legally drink. Now, Hunter Hayes has met Hank Williams Jr. and Johnny Cash, recorded with Lady Antebellum, written for Rascal Flatts, and dueted with Jason Mraz. Did we mention he's only 24? Who knows what Hunter Hayes is going to accomplish before he hits 30, because there isn't much left that he hasn't done already.
