I think, whoever direct TWICE vocal is a GENIUS! the usage of technique in every song is not overwhelming, but at a portion that really fit to every song
They performed in their concert lots of songs from this album, such as: -Scientist -Moonlight -Icon -Real You -Espresso -Rewind(momo popped off literally speaking here..it was so unexpected) -Cactus -Push& Pull(Jihyo, Sana, Dahyun) -Hello(Nayeon, Momo, Chaeyoung) -1,3,2(Jeongyeon, Mina, Tzuyu) - personal favorite performance of the concert along with Queen!!! Mina and Tzuyu were INSANE for this!! So sad Jeongyeon couldn't attend the concert:((( I wanted to see her doing that so bad -The Feels I recommend you watch them on your own(you can find fancams on youtube) when you finish listening to the whole album...It was a really nice experience!! The only thing that bothered me it was that Cruel and Last Waltz(my favorite songs on the album) weren't in the setlist...And they performed 35 songs
Cactus was actually about jihyo's cactus, aang, who died because she forgot about it. The song is aang's perspective during the time it was still alive. It's actually very funny when people gets emotional with this song without knowing the whole story. Btw, jihyo wrote and directed this song.
