"To my Laotian friend ", a musical and presentation form mixing between soloists, choirs, lyric in Vietnamese and Laotian, popular musical instruments and chamber music instruments... The whole coexists in a short work, melodious, one of the most requested on Vietnam Radio in the 1960s. Written after a tragic event marking the escalation of the war in the north of Vietnam, but the composer still keeps his style unchanging: beautiful music, beautiful characters, neat lyrics, perfect musical techniques, in tune with current events but far from propaganda! THE style of Hoàng Vân.
