Stop at Gravity and TREI can look like a quiet vocal group. Go on to the Dance Practice and to the Choreography Video for Deep and you meet a trio that turns the fine detail of the sound into movement.
The official channel does not carry a large number of videos, yet MV, Dance, Performance and Stage are all present. Watching across the types gives a truer picture of the group than lining up many copies of the same footage.
Editors' take The MV for Gravity followed by the fixed version of the Dance Practice is the quickest pair for understanding TREI.
