As of March 8, on the Ticketbox ticket sales system, Sister Who Makes Wave concert has sold out in 5 areas, including Gio em 1, Chuyen minh ruc 1 and 2, Dao dem ruc 1 and 2.
The remaining 21 ticket categories have not been fully booked, all of which are ticket categories with higher prices, from 1,500,000 - 8,000,000 VND.
After 3 days, tickets were sold mainly in the area with the lowest price of 800,000 VND. The producer continuously revealed special performances and interesting highlights in the concert to attract ticket buyers.
Compared to the Call Me by Fire concert that sold out within 40 minutes - 60 minutes, Sister Who Makes Wave's show had a rather slow selling rate.
In fact, if we compare the indicators of views, discussion, YouTube achievements... the "Sisters" are somewhat inferior to the "brothers" from the beginning of the season.
After about 3 months of broadcasting, the "Sisters" cast of season 2 has not had a solid general and private fan community.
Because, to organize a concert to attract fans, there need to be 2 factors: a program with many supporters and each individual has their own fan community.
Except for some famous singers such as Minh Hang, Toc Tien, Trang Phap or a group of famous stars such as Lan Ngoc, MisThy, Gil Le, the remaining "Sisters" have few "hard" fans, who can support long-term and spend money on promotional activities.
Season 2 was already commented to be "less hot" than season 1, while season 1 has ended for 1 year, causing the show to face the situation where season 1 is old, season 2 is not explosive.
In objective terms, the absence of Phuong Thanh (season 2) and the singers who made a good effect for season 1 such as Hong Nhung, Le Quyen, Uyen Linh will also make a part of the audience consider deciding to buy tickets to watch.
The Sister concert took place on April 12, near the day of the Call Me by Fire, Say Hi Brother concert. The fact that the "Sisters" concert sold out later was also a factor affecting the ticket sales rate.

However, with the reputation of being one of the music events that gathers the most female artists in Vietnam to date, the Sister Who Makes Wave concert is still a notable event in the first half of 2025.
48 Sisters are announced to have many familiar faces to the audience such as singers My Linh, Thu Phuong, Ngoc Anh, Minh Tuyet, Doan Trang, Pham Quynh Anh, Toc Tien, Minh Hang, Trang Phap, Diep Lam Anh...
Up to now, the producer has revealed that the music night will have the famous song "Da khong yeu thi thoi" by Minh Tuyet; the performances of female stars born in 89 can gather Trang Phap, Toc Tien, Huyen Baby, Diep Lam Anh...
The Sister Who Makes Wave concert is certainly still a large-scale, anticipated music event. However, to be able to sell all remaining ticket categories within 1 month, the producer needs to have a promotional strategy, revealing many more interesting performances to create their own color.
