Dunno. Even though they toured together they never did a collab that I know of.
It'll be interesting, though, to see how their new deal with Capitol turns out.
HUGE BABYMETAL NEWS! They have signed with Capitol Records and their new album, "Metal Forth", is coming out June 13 and will feature collabs with Poppy, Electric Callboy, Spiritbox, Tom Morello, Bloodywood, Polyphia, and Slaughter To Prevail. Kobametal is now CEO of BABYMETAL WORLD, LLC.
