From superheroes to presidential elections, 2016 seems to be a year of infighting and rivalries. It has even trickled down into Japanese rock, as Sugizo and Inoran, the two guitarists from renowned rock act Luna Sea, went toe to toe with their respective solo bands in their first double headliner show together on June 9 at Zepp DiverCity in Tokyo.

Appropriately titled "Sugizo vs Inoran presents Best Bout," the show was the first time the two guitarists performed at the same show as solo acts. This double billing was allegedly four years in the making.

When a member of a famous group that strikes out on their own, there's always a balancing act with regards to live performances of their own material and the stuff they're known for with the band. Play it too safe and the fans will end up questioning if there's a difference between the two projects, but venturing out too far brings up questions of just how much that member contributed to the group in the first place.
