It’s never too early to start making plans for the annual LOCK’N music festival at the Infinity Downs & Oak Ridge Farm in Arrington, VA. The line-up is official and, as usual, it leans heavily toward the jammier side of rock spectrum, with the Grateful Bob Weir, Mickey Hart, and their Dead & Company featuring John Mayer on guitar setting the tone at the top of the bill in the coveted Saturday and Sunday headlining spots. The four-day festival, which runs from August 23 through August 26, also features such artists as Sheryl Crow, Blues Traveler, the Tedeschi Trucks Band, Toots & the Maytals, and the local group Firecracker Jam.
