Although he's best known as a harmonica player, Charlie McCoy's credits as one of Nashville's greatest session musicians include playing guitar on Bobby Bare's 1963 "Detroit City" and trumpet on Bob Dylan's "Rainy Day Women #12 & 35." In addition, McCoy was a member of the instrumental group Area Code 615 and participated in the sessions for 1966's long- out-of-print Moldy Goldies — an all-covers record that's the Nashville equivalent of David Bowie's Pin Ups. Joining McCoy tonight is singer Elizabeth Cook, whose 2010 full-length Welder stands as one of the most intelligent country records in recent memory. A songwriter with a feel for the way pop culture intersects with tradition, Cook is a modern marvel. Rounding out the bill is singer Laney Hicks, who made some fine singles for the Monument label in the ’70s and has worked with McCoy for many years.
