Varian is starting a band, what instrument do major lore figures bring?

Illidan shows up with an accordion, cause who else?
Drek’thar shows up with a bass guitar, but he’s forever salty about not being able to play the drums
Malfurion comes in yodeling, which is a major point of contention to Varians death growl.

Who else comes for try outs?

Varian would play steel pan drums just for the shock factor that when you saw him bring them thinking he would be there to play death metal they would produce that relaxing tropical sound.

Mekkatorque shows up with an electric cello.
