On April 21st, Thrill Jockey will release the first Tortoise album in half a decade. The as-of-yet-untitled disc will not consist of one long piece as the band had originally planned, but will instead be a collection of varied pieces, with some that might include traditional songwriting elements such as verses, choruses and bridges. The band's previous studio album of all original material was 2004's It's All Around You.
Avant-metal act Isis will also have a new release on April 21st--on vinyl; the digital versions on May 5th--via Mike Patton's Ipecac label. Speaking to Billboard, vocalist/guitarist Aaron Turner called the upcoming Wavering Radiant "a little more orchestral in feel" than their previous albums. Tool guitarist Adam Jones guests on two tracks.
