Apologies that I'm relying on machine translation but some of it is pretty clear.

First, a reminder that Gal Metal is a rhythm game from DMM for Switch and the executive producer of the game is Tak Fujii.
Here is the TGS trailer for the game: https://youtu.be/a8NrocyszYM
The premise of the game is that you are in a highschool girl metal rock band that has to save the world from invading aliens.
Your band is K.M.G. the Kichijoji Metal Girls.
You play as the drummer, there is a left guitarist, right guitarist, keyboard and bassist as pictured here:
The game has a story mode, with regards to gameplay you use motion controls to play the drums as you are the drummer of the band.
Your right Joy-Con is for the bass drum, your left Joy-Con is for the snare drum, if you shake both simultaneously it hits the cymbal.
Went and quoted this part which explains how you play it and how the scoring system works:
Another quote regarding how Tak Fujii wanted to make sure the game was enjoyable to play, not much detail though:
Here is a picture of Tak Fujii himself doing the presentation of the game at TGS, he did perform but there wasn't a livestream unfortunately.
The Famitsu article states the game is single player, it will come out in February 2018 and will have both a retail and digital version. Price: TBD
Edit: There's some more details in the article if you are able to read it, there's also a slideshow of more pictures from the presentation here: https://s.famitsu.com/images/000/142/334/59c37ec39d4ec.html

In general sound gauges, button input is performed according to flowing notes, but the system of this work is quite special. Various rhythm patterns are prepared, and scores are added by playing them in combination. No musical score is displayed on the screen, and the player plays his / her favorite rhythm pattern according to music with his own ear. In other words, you can combine your favorite rhythm at any time and play it.
However, in order to achieve a high score, it is necessary to generate not only the accuracy of the rhythm but also the combo by a combination of rhythms, and finding a combination of rhythm patterns that are good at yourself and rhythm patterns that can aim for high scores.
Another quote regarding how Tak Fujii wanted to make sure the game was enjoyable to play, not much detail though:
Mr. Fujii talked about the feeling that "I was particular about the enjoyment of playing" about this system.
