Hải Ngoại Thương Ca / Loài Hoa Không Tên / Hái Hoa Rừng Cho Em / Một Lời Đã Hứa

Released in 1967 by the influential Sơnca label in South Vietnam, this record captures a pivotal moment in the development of contemporary Vietnamese popular music. The compilation brought together four of the era's most prominent female vocalists—Thanh Tuyền, Hoàng Oanh, Hà Thanh, and Giao Linh—to perform tracks that balanced the melancholy of wartime separation with the traditional aesthetics of Bolero and lyrical music.

The Sơnca label, spearheaded by producer Nguyễn Tất Oanh, was instrumental in shaping the sound of the mid-1960s, focusing on high-fidelity pressings and sophisticated arrangements that catered to an urban audience. The design and curation of these records were intended to provide a sense of cultural continuity during a period of significant social upheaval, with the featured singers becoming cultural icons for their ability to articulate the collective longing and emotional landscape of their generation.
