Mike Cooley, Patterson Hood, and Jason Isbell in The Secret to a Happy Ending, Barr Weissman’s “love letter to rock and roll,” starring the Drive-By Truckers.

It’s been nearly a decade since Southern Rock Opera — a perceptive, engrossing, and very loud meditation on Lynyrd Skynrd, race relations, and growing up and getting out — brought the Pitchfork crowd into the ever-broadening tent of Athens, GA’s Drive-By Truckers. Maryland-based documentarian Barr Weisman’s new DBT documentary, The Secret to a Happy Ending, will make its world premiere Sunday afternoon at the AFI Silver Theater. (It was originally booked for Feb. 5, but there was this little snowstorm.) Founding Truckers Patterson Hood and Mike Cooley, as well as Weisman and long-serving DBT drummer Brad Morgan, will be on hand to take questions following the 5:30 screening on Sunday. Another screening will follow at 8:30.

DCist reached Hood, an old pal of ours by now, in late January before a show in Mobile, AL to talk about the new documentary, still seeking a distributor.
