No matter how many times you hear guitarist, producer, singer/songwriter David Rawlings play his trademark 1935 Epiphone Olympic arch top guitar, you’ll ask yourself the same thing listeners have been asking for years: How does he do that? Best known as the longtime musical partner of Gillian Welch, Rawlings’ graceful instrumentation and seamless harmonies have long earned him the respect of musicians and fans alike. He stops at The Shedd on tour in support of A Friend of a Friend (Acony Records, November 17, 2009), his first recording. Dave Rawlings Machine is Dave Rawlings and five piece band, including Gillian Welch.
