The news was announced in a Warp news item:
“Battles and Tyondai would like to let their fans know they have chosen to follow their own musical paths.
Due to Battles’ ambitions of finishing their second studio album followed by commitments to a full touring schedule in 2011, and Tyondai’s own commitments as a solo artist and his desire not to tour, both Battles and Tyondai have decided to move on without each other.
It is a sad but amicable split.
Battles wishes Tyondai all the best.”
