Appearing locally as part of a July/August tour that will also take him to Louisiana, Missouri, Nebraska, Wisconsin, and Minnesota, the Austin-based singer/songwriter Walker Lukens plays a Daytrotter concert on July 6, the artist having been called “one of the best songwriters in Texas” by the Free Press Houston, “wonderfully inventive” by NPR World Cafe, and even, according to his hometown newspaper the Austin Chronicle, “a non-sexually-intimidating version of Prince.”
