"Warchest" (Capitol/EMI) features more than six hours of digitally remastered content, hand-selected by Dave Mustaine, including 30 audio and video tracks making their global release debuts, and an additional three tracks that have never before been released in the U.S. "Warchest"'s release caps Mustaine and Capitol/EMI's in-depth MEGADETH catalog remastering and restoration campaign, which has encompassed the band's Capitol studio albums, while also adding new audio and video collections to the band's arsenal. Armed with digitally remastered career-defining album cuts, soundtrack and compilation sides, unreleased live and studio performances and interview clips spanning more than 20 years, "Warchest" is the ultimate MEGADETH compendium. Included in the trove are a full 75-minute live set from a night on the 1990 "Clash of the Titans" tour and a DVD of highlights from a 1992 stop supporting "Countdown To Extinction" — two historical shows, both making their release debuts on "Warchest". The set's custom "vac-u-form" packaging showcases a 3-D ammo belt on its front and a 36-page booklet with an essay by Ian Christe and a comprehensive discography, complemented by an array of photos and images. Dave Mustaine says, "This is, by far, the best and most comprehensive look at all-things-MEGA if you had to get a crash-course in metal! With some of the most famous, and infamous, shows and any of the fluid, or flammable, line-ups, listening to this box set when it was all done was an adrenalin surge. I have got to hand it to my past band mates, they played great for how turbulent times could get in the blink of an eye, and I absolutely love every moment of this collection." MEGADETH's September 22, 2007 concert at the Newport Music Hall in Columbus, Ohio was streamed live via YeboTV.com.
