One constant throughout the five-decade career of veteran North Carolina fiddler Bill Hicks has been his duo performances with his wife, Libby, an accomplished guitarist and country/ blues singer. Bill's other exploits have at times received more attention; he co-founded the now-legendary Carolina country-folk group the Red Clay Ramblers back in the early '70s, and this summer he released a quartet record titled You've Been a Friend to Me with his Red Clay mates Jim Watson and Mike Craver, plus banjo player Joe Newberry. Friday, though, it's Bill and Libby sharing the spotlight again, in the latest installment of WUNC's Back Porch Music on the Lawn summer series. —Peter Blackstock
