Grandaddy have announced a box set celebrating the 20th anniversary of their breakthrough 2003 album, Sumday. Sumday Twunny is a limited 4xLP box set that’s out September 1 via Dangerbird. It features a remastered version of the original album, plus the four-track demos and a set of rarities and B-sides. The entire Sumday: The Cassette Demos collection is available to stream below.

Grandaddy’s Jason Lytle discussed the album in a statement:

After many years of hammering away at writing and recording as Grandaddy, Sumday seems to be the center of it and where it all peaked. To the journalists we were, “On the verge of greatness, underrated, overlooked, unsung.” It was a tumultuous and exciting time for us for sure. Also very exhausting.

Revisiting this material and reflecting on those times has been a double edged sword. Bittersweet is an apt word, I suppose. Twenty years after the fact, I’m just grateful to be alive and kicking… celebrating that moment in time by re-releasing the original album, B-sides and extras of that era, and even some raw cassette demos of the album itself a sort of sketchbook/rough draft of the LP in cassette form. So be it then. “On the verge of greatness, underrated, overlooked, unsung.” This is what all of that sounds like. I’ll take it.
