A little rain didn’t dampen the spirits of those attending or performing at the 2015 Louis Armstrong’s Wonderful World, a day-long party to celebrate Armstrong’s musical legacy. Throughout the afternoon of Saturday, June 20, the festival’s stage — located in Queens’ Flushing Meadows – Corona Park — saw performances by Ms. Lauryn Hill, Antibalas, Ozomatli, Rebirth Brass Band, and the Shannon Powell Traditional All-Star Band.
