YFN Lucci establishes himself as perhaps Atlanta hip-hop’s unlikely king of the piano ballad on the sequel to his 2015 debut. Gentle ivory-tickling productions power songs like “Who I Do It For” and the Young Scooter collaboration “Bloodshed” with mournful melodies that tap into the persistent emotion in Lucci’s voice. Wish Me Well 2 isn’t all sad songs, however; Lucci toughens up for the hard drums and screaming sirens of TM88 productions like “Woke Up (Boss).”
