Chuck Berry and Buddy Guy have taken essentially opposite approaches to their twilight years. Berry spent money badly and got entangled in messy weed busts long after he should’ve known better (that is, in his ’60s)—finding time in between to field accusations of having filmed dozens of micturating women in his nightclub. Guy took the classy approach, wearing polka-dot suits to match his Telecaster and, ever the statesman, bestowing patronage (and stage time) on up-and-coming bearers of the jackknife-blues torch. (Berry’s trajectory was arguably more rock ‘n’ roll, but Guy sure saved a lot on legal fees.) Genial relics both, they’ll join such acts as Jimmie Vaughan (you’ve probably heard of his brother) and Bonerama (they’re a horn band, and a good one) at the Chesapeake Bay Blues Festival this weekend. B.B. King and his folding chair will not be in attendance.

THE FESTIVAL TAKES PLACES SATURDAY AND SUNDAY AT SANDY POINT STATE PARK, 1100 E. COLLEGE PWY., ANNAPOLIS. $50-$90. (410) 257-7413.
