Review Summary: Not So Hidden And Not Much Of A Treasure3 of 4 thought this review was well written
Since 'Hidden Treasures' is comprised of Megadeth music that has never officially been on an album, I will treat it as an album and not a compilation. This might make things slightly unfair, but Dave Mustaine decided it'd be a good idea to gather these songs and put them together, so I should be able to judge his work, be it on an official release or not.
The track order seems a little weird at first; why it both starts and ends with covers I have no idea. Again, I know that since this wasn't an official album, there wasn't quite as much effort put into this sort of thing, but it would've made more sense for the covers to be towards the end of the album, as it means you'd immediately get some new Megadeth to listen to. That aside, the covers themselves are done safely, but efficiently and benefit from great production and a solid performance.
So, onto the originals, I can see why some of these were left out of official albums; 'Angry Again' is Megadeth trying too hard to be heavy and ends up sounding like a bad Pantera song and 'Diadems', while quite passionate, doesn't really lead to anywhere and isn't very memorable except the opening guitar line. 'Breakpoint', however is the thrashiest Megadeth song since 'Rust In Peace' ended, which makes sense as it was a Japanese bonus track on 'Countdown To Extinction', when Megadeth were turning away from thrash metal. The other two songs, '99 Ways To Die' and 'Go To Hell' are also worth hearing and should've appeared officially on an album. There seems to be one style present throughout the album here, and that is mid-paced 'British Steel'-esque heavy metal, which surprisingly suits Megadeth very well considering Dave Mustaine's unique vocal style.
To summarise, this album is hardly an essential purchase; you can get better songs from every album Megadeth made before releasing this and if you've been collecting Megadeth albums, singles etc. then you probably already are in possession of most of these tracks. If you haven't heard these songs though, don't buy this unless you really want to own Megadeth's whole discography, as you may be disappointed by a few songs (which means a lot for an album that isn't even half an hour).
