Bionic Band

I thought it would be interesting to make a band using weapons as instruments.

Onua is the one singing here, and the Protector of Jungle is playing the Violin. Kulta has an electric guitar, Kopaka is playing a cello, the Protector of Stone is playing an electric piano, and Ekimu has an acoustic guitar. 

Here Nex 3.0 is playing the drums.

The Lord of Skull Spiders is singing, and Furno is playing a trumpet.

What's your favorite instrument? Please comment.
