On their latest collaborative effort, Nhu Giac Chiem Bao, Tuan Hung and Le Quyen share a dream: to belt out on the poppy, syrupy hits. Because of their raspy, authoritative vocals, the two have done rather well on the solo tracks. Le Quyen comes off bittersweet and sultry on Luong Bang Vinh’s “Dang Cay.” Likewise, Tuan Hung sounds sentimental and tormented on Hoang Trong Thuy’s “Doan Khuc Cuoi Cho Em.” As a duo, however, they aren’t quite compatible. On Tuong Van’s “Hanh Phuc,” they both sound bored and dreary. Because their voices share similar qualities, they don’t have enough contrast to complement each other. Yet what bring the album down aren’t their vocals, but the lackluster, mechanical productions.
