Before Led Zeppelin, Robert Plant had formed a short-lived group called the Band of Joy. He's now revived the name, this time with famed singer-songwriter Patty Griffin, singer-guitarist Buddy Miller (from Plant's Grammy-winning Raising Sand project with Alison Krauss), plus Darrell Scott, Byron House and Marco Giovino. Sounds like a stairway to rock heaven. Tuesday, Feb. 1 at 8 p.m. At DAR Constitution Hall. Tickets are $64.25. Call 202-265-0930 or visit 930.com.
