As reported on Blabbermouth:
Seminal technical metal pioneers ATHEIST have regrouped for a run of exclusive live performances.

Guitarist/vocalist Kelly Shaefer has reassembled what is widely considered the band's classic recording lineup (Shaefer, guitarist Rand Burkey, bassist Tony Choy, and drummer Steven Flynn) for two exclusive festival performances; Italy's Evolution Festival and Germany's Wacken Open Air. Shaefer comments, "We're very excited to be able to get back on the stage and play these insane tunes hit the air again the proper way with Flynn, Burkey and Choy. It's going to be very exciting and something not to be missed!"

ATHEIST will take part on Evolution Festival (scheduled for July 16 and 17 in Brescia, Italy) and Wacken Open Air (scheduled for August 3-5 in Schleswig Holstein, Germany). These will be the first in a series of exclusive festival performances announced. Shaefer continues, "We would like to make a great festival run this year and expose as many as possible to the music we lived and died for. Many thanks to the Evolution Festival and Wacken for helping to give many people who never got to see ATHEIST live a chance to see us one last time. This is our chance to make the music we worked so hard to create come alive one last time, and we guarantee that it will not disappoint."
