To mark its 15th year of existence, Scottish post-rock band Mogwai will reissue its 1999 record Come on Die Young on June 16 via Chemikal Underground. The reissue includes over an hour of newly added material, including demos, early recordings, unreleased tracks, rarities, the 2001 Travels in Constants Vol. 12 EP, and more. Hear a remastered early take of "Ex Cowboy" above.

The record will be available as a 4xLP boxset, 2xCD, and digital download. Check out the boxset tracklisting below (the order of the CD's tracks varies slightly). The reissue also comes with a show poster.

Mogwai are touring North America this spring.

Before Deafheaven put out their 2013 epic Sunbather, they released a great cover of Come On Die Young's opening tracks "Punk Rock" and "Cody"—listen here.
