Battles' October 26th show at (Le) Poisson Rouge has been canceled, to be rescheduled for sometime later in the fall. No explanation has been given as of yet, though maybe the delay is related to the ongoing recording of their second album. "All tickets purchased online will be refunded immediately. If you purchased tickets in the box office at the venue you can bring your ticket to the venue for a full refund."
The band's London show four days later seems to still be on (though that could change).
