Some even refused to stop the ongoing session when the Communist shells exploded all around - at ARVN 17th Armored Reconnaissance Cavalry in Quang Tri 1972, for example. The teams and their songs really indicated the surge of people's morale before being defeated in 1975. After 1975, nearly 2 million Vietnamese mostly from the South left Vietnam for Western countries. The Vietnamese communities abroad have helped preserve the great treasure of beautiful songs and continue promoting Vietnamese music. Thanks to sophisticate sound equipment, pre-75 and newly composed songs could be recorded on CD disks, video tapes and audio cassettes at low prices.
Music production is a lucrative business among the Vietnamese communities abroad.
Moreover, those tapes and disks have been invading Vietnam at a large scale. Meanwhile, the reverse flow from Vietnam is much smaller. Many younger composers in Vietnam and abroad are emerging. Those abroad continue the pre-75 trend with new influence from Western music. Meanwhile, their counterparts in Vietnam are still restricted within the Party policies concerning culture.
