In February of 2018, she gave her listeners more of her distinctive sound that Questlove dubbed "soul-appella" when she self-released Finding Foundations: Vol. II. Her SXSW 2018 debut led legendary KCRW DJ Anne Litt to remark, "there's some sort of joy and beauty in the way that she performs that really drew me in all that much more." Pitchfork Magazine followed this up by declaring, "Madison McFerrin is making a cappella cool again" in a Rising Artist profile. She subsequently performed at Pitchfork's Rising Artist showcase at Northside Fest, OctFest, Paris Avant Garde showcase and inaugural Midwinter Event at the Art Institute of Chicago. Along with these noteworthy performances, Madison has also dazzled European crowds with her one-woman show of looping hypnotic harmonies live from London to Poland.
Beyond the stage, Madison's one-of-a-kind vocals can be heard in episodes of Comedy Central's Broad City and HBO's Random Acts of Flyness.
This year, Madison plans to build upon this momentum by pairing her timeless voice with modern production on her new project, You + I, which quickly had its lead single "TRY" rack up 500K+ views in her debut COLORS session.
