Well, honestly you should buy both, but first buy the studio Dark Side Of The Moon. In my opinion you should start off with the original, and work your way into the live version, because once you become accustomed to hearing the studio version, once you hear the live version(without Roger), you're gonna be like "Oh wow, this is different..............and this part's different to!". Trust me, I did this when I got into Pink Floyd, I loved it.
