2001–02: Nhật thực (Solar eclipse)

In 2002, Hà Trần and musician Ngọc Đại held Nhật thực (Solar eclipse) live show throughout Vietnam to introduce the same album – Nhật thực. The live show was designed with all songs written by Ngọc Đại and lyrics from poems of Vi Thùy Linh. Besides, this show was also contributed by composer Đỗ Bảo, singers Minh Anh – Minh Ánh (2M band), choreographer Quỳnh Lan, vision director Việt Tú and the stage decorator Trần Vũ Hoàng (Hà's brother).

"Nhat thuc" faced a burden of troubles with its commencement. There was a scandal of copyright dispute between Ha and Hồng Nhung in respect of song- "Det tam gai" (Weaving Tam Gai), Ngoc Dai then stopped Hong Nhung to perform this song. However, in December 2001, Nhật thực was hindered by the Performance Administration because the lyrics was so "sexy" that they may "cause bad effects to the culture and ethic of Vietnamese music" (said Mr. Lê Nam – Director of the Administration). Therefore, the album was delayed, so that the artist could remove and amend its lyrics. 2 songs – "Tự Tình" and "Mơ" (Dreaming) – used to be the starting songs in this concept album and were removed; the lyrics of 2 songs "Cây nữ tu" and "Đừng hát tình ca du mục nữa" (Don't sing the nomad's love song) were changed.

After settling the above matters, the show took place in April 2002, and then Nhật thực album also went public in May. Nhật thực album includes 7 songs: "Nghi ngại" (Shadow of doubt), "Đừng hát tình ca du mục nữa" (Don't sing the nomad's love song), "Phía ngày nắng tắt" (Other side of sunset), "Dệt tầm gai" (Weaving Tam Gai), "Tiếc nuối" (Regret), "Ảo ảnh" (Illusion), "Nhật thực" (Solar eclipse). The two songs "Mơ" (Dreaming) and "Tự tình" were removed, and the album with 9 songs then had 7, and "Cây nữ tu" was changed under new name of "Ảo ảnh". Nhật thực was one concept album, with a completed story. 7 songs expressed 7 stories told by a girl in love with her desperation, doubt, regret and obsession.

Right after release, Nhật thực made a shock to Vietnam's music with its strange and new trend, including lyrics, melody, performance art and arrangement. This show became a special music event and was voted by presses as one of the most important cultural phenomena of 2002, a landmark of innovation in music in terms of its original style and performance in Vietnam. In additions, the existence of Nhật thực oriented the music audiences in Vietnam to be interested in music harmony, arrangement and mix of an album. Nhật thực was also an important step in the career of Ha Tran, causing prominent development of her style: Stronger, Special and Diversity. As from Nhật thực, Ha was called as one of 4 divas of Vietnamese music.

Nevertheless, after success of the first show, dispute arose among the members of the show, Ngọc Đại – Trần Thu Hà – Vi Thuỳ Linh. As a result, after Nhật thực 1, Trần Thu Hà announced to the press that she had quit Nhat thuc. Ngọc Đại continued with his own Nhật thực 2 in 2003, without Ha Tran and Vi Thuỳ Linh, but there were many stars of Vietnam such as: Thanh Lam, Hồ Quỳnh Hương, Linh Dung, Tùng Dương, Khánh Linh, Ngọc Khuê… However, "Nhat Thuc 2" live concert and the album (sold at special price of VND 6000, equal to about USD 0.5) did not get any success as the first one.
