Other scheduled events include a movie poster exhibit, 5K run, motorcycle ride and classic car show. The music begins at 4 p.m. today with McClinton and Roomful of Blues on the bill. The show cranks up at 1:30 p.m. Sunday with Moore, Fontana and McDowell joining the eclectic lineup. The daddy of Elvis festivals, Elvis Week, kicks off Aug. 10 in Memphis and concludes on Aug. 16, the day the singer died in 1977.
