Hidden Treasures gathers songs Megadeth recorded outside the studio albums in the early nineties: contributions to films and games, plus a handful of covers. 'Angry Again' comes from Last Action Hero, 'Go to Hell' from Bill & Ted's Bogus Journey and 'Breakpoint' from the Super Mario Bros. film. Alongside those are versions of songs by Black Sabbath and the Sex Pistols. The collection first appeared in 1995 as a standalone EP. This edition is an LP on purple and black marbled vinyl, released for Record Store Day.
