LA’s long-running Cambodian psychedelic rock group Dengue Fever recently released their sixth full-length album, “Ting Mong.” It is their first new release in eight years, and showcases the band in a more relaxed, reflective mode than previous records — a perfect platform for the nimble voice of lead singer Chhom Nimol. As part of the series and podcast “Movement,” Meklit Hadero talks with Nimol about how she developed that unique voice, singing with her family in a refugee camp and later on Cambodia’s first televised music competition.
