How a band fills out its credits
Members' names appear as writers on all six tracks. 'Mind' was composed by Lian and Dane together, and 'Thinkin' About You' by all the members.
For a band, credits are not a list but evidence. They record exactly who made how much. Being credited as writers on every track means the whole album came from inside.
It is five months since their last release. In that time they made six songs and filled the credits.
A guest on the title track
Sungchan of RIIZE came in as featured artist on 'ALIVE'. An idol group member lending a voice to a band's title track.
When another team's vocal enters a band sound, the grain of the song bends once. A familiar voice is set over an unfamiliar arrangement.
'ALIVE' is electronic synth-pop. Where a guitar band's sound meets the texture of synths, there is one more guest.
Which way the six songs scatter
'Mind' is synth-pop, 'Thinkin' About You' is retro, 'First Daylight' is modern rock. 'Play My Guitar' calls the guitar by name in its title.
Synths and guitars alternate across one album. 'MOMENTUM' in the album title means the tendency of something already moving to keep moving.
The name says second wave after the first, and the word inside it is momentum. Continuing, said twice.
What to check today
Start with the title track. Where the band's sound and the guest's voice meet is the first thing to check.
Then play 'Play My Guitar' and 'Mind' back to back — the two songs that push guitar and synth to the front.
Last, read the credits. The same names repeat across six tracks.
That's the last of the numbers. Now, the music.
