Black Star shows have been cancelled, possibly due to issues with Live Nation. They'll be debuting new Black Star/Madlib material for the Colbert Report on October 5 (replacing the NYC date of their cancelled tour).
Due to situations beyond their control, The Exit has been forced to cancel their west coast tour that was planned for the month of May. However, the band will begin writing their next record in May and have some tour dates with the RX Bandits shaping up.
The east coast part of The Panic Division, Aphasia, and The Transit War's tour has been cancelled due to van problems. The Transit War also lost a bunch of files in the studio so they have to go back to the studio to re-track some songs.
