On his 2018 EP, The Faded Red and Blue, David Berkeley sings about some of the country’s most hot-button issues, including immigration, the environment, and gun violence. If such a thing is possible, the songs’ melodies merge with his lilting yet resonant voice to create musical poems that are almost too beautiful to contain such darkness. Berkeley plays at 5:30 p.m. on Friday, July 5, as part of the Sunset in the Garden concert series at Santa Fe Botanical Garden (715 Camino Lejo). General admission is $10, with discounts available; children under 6 get in free. For more information, call 505-471-9103 or go to santafebotanicalgarden.org.
