Sunday was a day to remember and a finale for noted saxophonist J. Plunky Branch. The soulful musician has been giving solo porch concerts outside his home on Rosewood Avenue near Byrd Park in the city’s West End for the past 90 days. The concerts helped lift the spirits of neighbors, friends and others during the coronavirus pandemic. On Sunday, Mr. Branch celebrated his birthday with a final porch concert, which drew about 100 people who set up lawn chairs along the shady street and median to enjoy the music of Plunky & Oneness, his group.
