So what exactly is this site,anyway, you may ask? Well, as you can probably tell by the name, The Riff Repository, it has to do with metal and/or hard rock. In fact, you'd be right in that assumption.
Have you ever picked up a popular rock/metal magazine like Revolver or The Hit Parader, and looked at some of that magazine's coverage? Chances are, the cover has some popular "metal" (notice I use the term loosely) group like System of a Down or KoRn as their main feature. Then, when you flip to the inside, you'll notice that largely all of the bands talked about are either A) Radio-friendly, over-exposed popular rock bands or B) Completely underground, obscure, and chances are, not very good "extreme" metal bands. I don't know about you, but I'm a fan of quality, talented metal music; I don't care what its popularity status is. While my definition of quality and yours is completely subjective, what The Riff Repository serves to do is bring you a middle ground between the radio-metal of MTV and the bands you'll never hear, or want to hear, for that matter.
The Riff Repository is a knowledgebase on all kinds of metal (and some hard rock that I deem worthy). Most of the information you'll find on this site is purely my opinion and not meant to be taken as the be all and end all. Why should you care about my opinion? You really shouldn't. But, you're here for the same reason you bought that Kerrang!: you like reading about metal and what other people have to say about it. The thing about the Repository is that there is no catering to corporate bullshit, no ads, and well, information about bands you care more about. Oh, did I mention it's free, too?
As of right now, The Riff Repository is the love child of one man, and as such, the site is not going to have all the bells and whistles or numerous updates as other music sites like Rock Detector or The All Music Guide. But on the other hand, the depth of content may just make up for that...
