Fans of the post-hardcore band At the Drive-In were treated to unexpected news this week as the band emerged from hiatus to announce a set of secret shows and an all-digital concept album consisting of 39 MIDI files.

The 39 songs will be released each week for the next 39 weeks.

Cedric Bixler-Zavala, the band’s lead singer, said the shift to “MIDIcore” is what the band had always been building towards.

“Fortunately, technological advancement on the MIDI sound front has captured pace and obtained the necessary capacity to fully fulfill the voluminous vision that the band had originally prognosticated,” said Bixler-Zavala.

According to the band’s website, the world tour will be a series of secret shows in the band’s hometown of El Paso, Texas., taking place in the span of 39 weeks, with the locations of each venue revealed through an elaborate scavenger hunt through the Vatican’s sealed archives.
