Britain's Declan McKenna made an auspicious debut in 2015 when his catchy lo-fi indie single "Brazil" became a major viral hit. By the end of that year, the 16-year-old singer/songwriter had won a major prize at Glastonbury and signed with Columbia. His knack for strong melodies and willingness to take on social and political issues were both apparent on his 2017 debut, What Do You Think About the Car?, which charted in both the U.K. and the U.S. McKenna's follow-up LP, 2020's Zeros, toned down the topical fare and focused on glowing glam rock vibes, reaching number two in the U.K.
