The singer-songwriter Indigo De Souza has quickly developed into one among indie rock’s most versatile younger voices. After she débuted, in 2018, with “I Love My Mom,” an endearing, albeit crude, grunge-pop revelation, her second album, “Any Shape You Take,” from 2021, introduced breadth to her songs of unsustainable love, smoothing out her sound and refining her lyrics, whilst she prolonged into new territory sonically and emotionally. On April 24, De Souza brings her bracing, catharsis-driven breakthrough to Music Hall of Williamsburg.
