Many Vietnamese pop singers are going acoustic.
Le Thanh Hai, the photographer and producer of Thanh Lam's unplugged album said, "The trend of music these days is to develop elements that highlight classical values of music."
Since the release of the popular female vocalist's acoustic album, two years ago, other vocalists have followed suit.
Album Acous'84 of Ha Anh Tuan, a local pop star, released in July was complimented by known songwriter Tran Tien.
Other musical stars such as My Linh, Le Hieu, Le Cat Trong Ly plan to go acoustic in their upcoming albums.
Songwriter Anh Quan said "Singing acoustic demands that the singer exercise good technique. It's not for amateurs." Quan is Linh's husband who has produced almost all of her albums.
Singer Le Quyen said three years ago, she didn't dare to sing acoustically. "It's not easy. The singer needs to know enough about techniques and how to control their emotions to sing out loud the quality of acoustics.
"I only dared try it after I felt I had matured a lot as an artist."
Globally, acoustic rock became popular following the television show "MTV Unplugged" during the 1990s. The trend was largely abandoned in the early 2000s. Nowadays, acoustic songs are included in albums - mostly as bonus tracks.
