Returning after a five-year gap (which, granted, included a box set and a collaborative record with Bonnie "Prince" Billy), Tortoise confronted a pair of age-old musical questions: does anyone really care about an experimental rock group after 15 years, and does said group actually have anything to say after that length of time? After all, the sound of rock's future circa 1994-1996 was beginning to sound tired by the time of 2004's It's All Around You, and the sense was growing that Tortoise should call it quits and begin accumulating enough years of inactivity to eventually be rediscovered, remastered, and reunited. Beacons of Ancestorship neatly squashes all those questions and assumptions, revealing a band that is just as fascinated with sound, just as intrigued by its myriad possibilities, and just as unerring in presenting those ideas in the form of entertaining instrumental music as when it debuted in 1993.
