Query: NOT THEIR BEST INDEED. NOT FOR BEGINNERS

I AM A VERY, VERY HUGE FAN OF VDGG, BUT I ADMIT THIS CD IS JUST FOR ULTRA HARD CORE FANS. IT INDEED HAS A COUPLE OF JEWELS, BUT THE SOUND IS TERRIBLE ON SOME TRACKS, LIKE BAD DEMOS. THE SOUND QUALITY AND MUSIC FROM THE STUDIO ALBUMS BLOWS THIS ONE AWAY.
