Post clips of K-pop idols playing musical instruments!

I was thinking the other day that I really miss having Kpop idol bands. Day6 is about the only active one left (FTisland and CNBLUE are laying low, and AOA Black died an early death. Wonder Girls disbanded.) I wanna see more Kpop idols playing musical instruments again! (And yes, I know there are instrumentalists in other genres of music, especially rock... but I specifically want to see K-pop idols who were trained to sing and dance primarily also play musical instruments.)

So, please post clips of your favourite Kpop idols playing musical instruments! Preferably 3rd-gen or later (I know the 2nd-gen has several capable musicians). Doesn't have to be official performances, can be behind-the-scenes or variety show stuff as well. I just want to know that musicianship is alive and well in Kpop, and not just in vocals or dance alone. I'll start off with three of my favourites:

As expected of the daughter of a piano teacher. Juhyun does her mother proud.

I want more Seventeen band

Who was the lead guitarist who was playing the electric guitar?! He was really good, especially at the end. Was he part of Seventeen band too, or did they bring in a session musician for that?

Quote from blingyblinger

I'm embarrassingly bad with instruments and telling what's coming from where

The long hair is Jeonghan and the other is Joshua but there's also a non member on the far right

Ah. Jeonghan was playing bass, and Joshua was playing rhythm guitar (he was strumming in a set pattern). The other non-member must have been the lead guitarist (plucking all the fancy electric guitar riffs). Still, Seventeen band did a great job.

It would be interesting if one day we complete the entire set of Chinese classical instruments. Maybe find an erhu player and a dizi player too. Then maybe guqin.
